P-FSM150S: a new Piezoelectric Fast Steering Mirror

January, 2022

The P-FSM150S is a new Piezoelectric Fast Steering Mirror which has been developed for Space Optical Communication, and which has been especially designed for very large scale constellations. The P-FSM150S was developed during ARTES project with CNES funding, in order to meet both ECSS space grade flight & low cost requirements for recurring production batch up to thousands of units. The design has been especially optimized to feature very low number of parts, with very fast manufacturing and assembly processes, together with optimized supply chain for large quantities of space grade optical mirrors. The very compact and light-weight design allows to withstand very high shock and vibration levels, while providing with +/-10 mrad large dual axis tilt amplitudes and high frequency control bandwidth. The P-FSM150S has successfully passed space qualification environments like thermal vacuum, vibration and shock testing. It is currently involved in a lifetime test demonstration at accelerated frequency and high stroke. This fatigue test already reached 3,6.10cycles at the end of 2021 without any failure and on the way to cross the 10 billion cycles beginning of 2022.


January, 2022

CTEC is pleased to announce the successful tests of the second qualification model of Tip Tilt Actuators (TTA). This APA500XXL actuator will be used in the stabilization units for the M5 mirror of Extremely Large Telescope (ELT). It displays 680µm of stroke and a stiffness of 70N/µm. The encapsulation of the piezo material has been successfully tested without any leakage detected. In 2021, this qualification model went through the lifetime tests: 22 Million cycles were performed successfully at full stroke. This result, combined with a good thermal behavior, allows CTEC to pass the Final Design Review successfully two months ahead on schedule. In 2022 CTEC will have to deliver the final Units. They shall be able to operate at least for 30 years.


Our new CMAµ10 a linear power amplifier for magnetic actuators

June, 2021

The new CMAµ10 drive electronic has been specifically developed for the driving of small size linear magnetic actuators, such as MICA20CS, as well as small size magnetic Fast Steering Mirrors such as M-FSM62. It is a low power drive electronic, based on low noise linear power amplifier, providing current and voltage up to 1A and 24V. The MCAµ10 is based on output current closed loop control, which is the best precise and fast approach for both force control, and position control, of magnetic actuators.  The MCAµ10 has been specially developed and tuned for resonant and frictionless flexure bearing actuators, such as MICA actuator family, in linear motion for proof mass applications, and in rotational tilting motion for the fast and fine positioning of mirrors, such as M-FSM actuator family for optical communication. The MCAµ10 is best applicable to any over small size magnetic actuators, in linear, rotational, or tilting motions,  such as voice coil and moving magnet actuators, and is especially relevant for applications requiring cascaded control, implementing in series the MCAµ10 inner current control with any customer controller based on customer sensors.

Piezo tip tilt platform DTT60SM-SG

June, 2021

The DTT60SM-SG is a piezo Tip Tilt steering Platform with 10 mrad peak to peak amplitude (+/- 5 mrad) along 2 orthogonal axes of rotation Rx & Ry. The unloaded resonance frequency is higher than 1.6 kHz which open large bandwidth steering mirror operations. This steering platform can welcome a large spectrum of mirror diameters up to 2 inches (~50 mm). As an option, CTEC can also provide the user with a specific mirror integrated and tested with the DTT60SM-SG platform.  Strain Gages Sensor (SGS) are bonded on each axis to monitor the angular positioning and the related SGS conditioner is integrated in the PCB platform. This embedded SGS conditioner allows the SGS positioning feedback signal to be non-sensitive to the external disturbances and to the cable length between the DTT60SM-SG and the controller. This is very useful for embedded Electro Optic systems where control electronics and optical payloads can be separated by long distance cable. The low capacitance per axis (3uF) leads to reduce the power consumption over a large control bandwidth. The CCBu40 controller box is recommended for using the DTT60SM-SG in dynamic condition with operating frequency up to 200 Hz at full stroke. The main applications are Fast steering Mirrors, micro-scanning, speed tracking, Anti blurring and Line of sight stabilization in embedded Electro Optic systems.

Philip BATES from Fusion for Energy is talking about CTEC rotative piezo motors based on MSPA:

“The In-Vessel Viewing System is a LIDAR metrology instrument designed for deployment inside the ITER Vacuum Vessel to assess any damage, erosion or displacements of the ITER Components. When deployed, it will face extreme environmental conditions, with 8 Tesla magnetic field as well as high temperature and neutron and gamma radiation. CTEC piezomotors were identified as an ideal technology to scan the LIDAR beam across the in-vessel components, however the lifetime and environmental requirements of ITER pushed far beyond the state-of-the art available from piezo actuators, and CTEC have begun the first phase of testing to demonstrate that their actuators can meet the reliability and lifetime requirements of the system. Environmental and radiation tests are foreseen in the near future, to confirm that CTEC actuators can provide the driving force behind inspection of ITER components.”

Position sensing: from Eddy current Sensor (ECS) to Linear end-stroke sensor (LES)

January, 2019

The position Eddy Current Sensors ECS developed by CTEC with the support of French Space Agency CNES are contactless sensors made of an Eddy Current Probe (ECP) with an associated conditioner. ECS electronics manage the signal from the ECP probe to provide a precise measurement of the probe-to-target distance with enhanced bandwidth reaching 20kHz.

Again with the support of CNES, applying experience gained with ECS, new Linear End-stroke Sensors LES1000 have been developed in 2018. They integrate the electronic circuit (with space equivalent components) inside the sensor back side to offer an all-in one solution. Due to their attractive performance, they have already been selected by ESA to fulfil needs for Contactless Micro-Switches !

Fine stepping piezo actuator FSPA

January, 2019

Fine Stepping Piezo Actuator (FSPA) is a patented actuator that combines SPA technology with mechanical reduction. This allows to achieve very small step sizes even down to 10 nm.

Another major advantage of FSPA is its ability to maintain its position,while unpowered, even when very large outer forces or acceleration are applied. Typical speed for FSPA is 200 µm/s.

Typical application for this actuator is to finely tune the position of a component and maintain this position afterward even though environmental conditions may get real bad such as during off-road transportation, space launch or aircraft landing…

Have a look to the technical datasheet of our FSPA35XS.

H2020 Project MC-Suite: successful results

January, 2019

Held over a period of three years, the MC-Suite project allowed the development of new generation of ICT enabled process simulation, and optimization tools. Cedrat Technologies’s contribution was to design, manufacture and test four different systems, in the fields of force sensing, vibration damping, and vibration cancellation.

In the last period of MC-Suite project, the MICA300CM Proof Mass actuator commenced a lifetime test at CTEC, with the objective of demonstrating a fatigue life far beyond 20000 Hours at full stroke (two billion cycles). This long duration test, which will be continued from now and for several years, is expected to qualify the Proof Mass for ultra-long duration operational conditions, with zero maintenance, such as within nonstop industrial machining processes or even space compressors for cryocoolers.

HPPA piezo actuator on-board the flying AEOLUS ALADIN Lidar

September, 2018

On 22/08/2018, ESA’s AEOLUS satellite was successfully launched into polar orbit on a Vega rocket. AEOLUS carries ALADIN, the first instrument measuring the wind from space ever built. ALADIN is a DOPPLER LIDAR using a Laser Transmitter (TXA) developed by GALILEO AVIONICA (presently LEONARDO).

In this interferometric application, the high power laser has both to emit frequency stable light and to be precisely tunable (for receiver calibration), which is contradictory.  To this end, a laser frequency control is performed by the dynamic tuning of the laser cavity (Master Oscillator) of the TXA Power Laser Head. To realise this tuning, CEDRAT TECHNOLOGIES (CTEC) has developed for GALILEO AVIONICA a Hollow Prestress Piezo Actuator (HPPA) which modify the cavity length by fine and fast moving the output coupler of the Master Oscillator.

Severe dynamic specifications were unusually required for this HPPA piezoactuator. The HPPA had to present a resonant frequency of about 30kHz to offer a bandwidth of 10kHz. Correlatively qualification required a very large number of cycles reaching 4.1010 cycles, which was passed establishing a new life time record. An additional lesson learnt was the need for Lot Acceptance Test (LAT) and Destructive Part Analysis (DPA) in order to secure and to comply with the quality process applied on the batch  of multilayer piezo ceramics from the Engineering to the Flight models. Thanks to LAT and DPA defined and applied by CTEC, any defects observed inside the batch samples of piezo ceramic parts with critical impact on the performances of the HPPA (dynamic, life time,etc...) have been unveiled. These LAT & DPA results were feedback to the partner supplier of the piezo ceramic batch in order to correct, to adjust and to improve accordingly its manufacturing process for making optimum quality parts. This LAT & DPA helped to strengthen the quality insurance on the critical part (piezo ceramic) and the partnership between CTEC, its supplier and client while solving any risk of project delay due to manufacturing quality issues on critical part like piezo ceramic.   

Since this event, ESA has entrusted the ECSS norms for the design and test of piezo actuators in space to CTEC. The experience gained by CTEC in ALADIN has been used to develop other HPPA actuators for SWARM mission (flying since 2013) as well as for the Beam Steering Actuator (BSA) of the ATLID Atmospheric Lidar for EARTHCARE satellite.  It could be useful also for other ESA future Meteorological missions using a LIDAR such as MERLIN.

Mécanismes à orientation rapide de mirroirs

Septembre 2018

Les mécanismes piezo de CEDRAT TECHNOLOGIES (CTEC) et leurs électroniques associées sont utilisés dans les applications de la défense aérienne et spatiale. On les retrouve dans les instruments optiques, les caméras, les télescopes et les systèmes électro optiques embarqués (avions, hélicoptères, drones, vaisseaux spatiaux, satellites). CTEC développe depuis des années des mécanismes à orientation rapide de miroirs (FSM fast steering mirrors) pour des applications de pointage laser dédiées au spatial et à l’optronique. Ces 10 dernières années, les efforts ont été portés sur des mécanismes piézoélectriques afin d’atteindre une performance de contrôle sur une bande de très haute fréquence pour de petits débattements angulaires (< 1°). Les applications naissantes en Europe, comme la communication optique laser, requièrent des débattements angulaires plus importants que ceux existants et qui ne peuvent pas être facilement atteints avec la technologie piézoélectrique. C’est pourquoi CTEC a développé une nouvelle gamme de produits « Magnetic Fast Sterring Mirror » (M-FSM) basée sur des actionneurs magnétiques à débattement angulaire important (~ 4°).

Nouveaux modules de moteurs piezo pas à pas MSPA

Septembre 2018

Les modules MSPA assurent des fonctions miniatures de micro positionnement rapide sur des courses illimitées en linéaire ou en rotatif : de taille typique de l’ordre du cm3, ces modules réalisent l’entrainement tangentiel d’une charge par frottement. La charge entraînée par un MPSA peut être aussi bien la partie mobile d’une glissière qu’un rotor. Leurs vitesses tangentielles d’entrainement peut varier de 0 à 50 mm/s. Leurs forces d’entrainement dépassent 1N. Hors alimentation, ils assurent un blocage à l’arrêt de la charge avec une force de maintien pouvant atteindre 10N. En dynamique, les modules MSPA produisent des micros pas contrôlables de 5 à 25µm par effet inertiel entraînant la charge par glissement adhérence. Les MSPA permettent de réaliser des moteurs piézoélectriques performants et fiables : les MSPA sont basés sur les Actionneurs Piézoélectriques Amplifiés APA®, composants à haute fiabilité bénéficiant d’un fort héritage spatial. Les MSPA peuvent fonctionner en ambiance vide et dans une gamme de températures allant de -270°C à +70°C. Ils résistent aux chocs et aux vibrations. Ils sont économiques et nécessitent qu’une voie d’alimentation. Les applications des MPSA concernent des micro-motorisations linéaires ou rotatives pour de la refocalisation, des goniomètres, de l’orientation d’échantillons, des obturateurs, des roues à filtres, des mécanismes de pointage. Le développement des MSPA est soutenu par BPI France dans le cadre du projet Eurostars ELVISA.

Development of magnetic fast steering mirror prototype for optical pointing applications

July 10, 2018

Fast Steering Mirrors are core products continuously developed by Cedrat Technologies (CTEC) for optical pointing applications, for Space, and Optronic domains. During the last decade, main development efforts where focused on piezoelectric mechanisms technology, in order to achieve ultra-high frequency bandwidth control performance over small angle strokes. New applications under maturation in Europe, such as laser optical communication, require much higher angle strokes compared to the existing state of the art, which cannot be easily achieved by piezoelectric technology. Therefore CTEC is focusing on the development of a new Fast Steering Mirror family based on high angle stroke magnetic actuators.

The first of a number of products being developed within the MC-Suite project has been undergoing testing, with excellent results.

The single axis force feedback table is able to measure loadings up to 20kN, however at the same time the rigidity of the system remains high, with a calculated stiffness of 3.05kN/µm in the vertical direction. The table is rated IP67, and with a diameter of 100mm by 70mm high, and a weight of 3.1kg remains compact.

View the video to see the table in operation!

The use of an ECS sensor allows the cost of this table to be considerably lower than existing tables using alternative sensor systems, furthermore the ECS technology is easily scalable, enabling greater loading or more axis of measurement to be easily achieved.

Further products being developed within MC-Suite include a single axis force feedback tool holder equipped with wireless data transmission and an active proof mass damper.

MC-Suite is funded by the European Commission under the Horizon 2020 Programme GA n°. 680478".

CLIMA project - Damping linkage design collaborative project – Successful annual meeting

June 19th, 2017

Cedrat Technologies is member of CLIMA project, funded under the FUI 19, involving 10 French partners, with a duration of 3 years.

The work of the project focuses on mechanical junctions, which are the main source of depreciation in many cases. The project aims to develop innovative technological solutions (damping bearings, self-locking nuts, damping collages, instrumented fixings, pilot fasteners) as well as specific software tools for the identification and prediction of damping in these junctions. The innovations generated by the CLIMA project must make it possible to reduce the risks of over-dimensioning of structures, which result from ignorance of precise dynamic behaviour.

Cedrat Technologies hosted the half project meeting (To+18m) in its facilities in Meylan. It has been the opportunity for the partners to discover laboratory and production means and capabilities besides presenting advancements within the project and especially the Micro controller demonstrator, for embedded closed-loop piezo actuators, developed with partners.

Cedrat Technologies wants to thank its partners for this efficient and fruitful meeting.

The Double Tip Tilt (DTT35XS) from CEDRAT TECHNOLOGIES (CTEC) is a piezo Tip Tilt Platform to move or to position a mirror along 2 axis of rotation. The purpose is to make either a Point Ahead Mechanism or a Fast Steering or a Beam steering Mirror. The first DTT35XS prototype was initially developed in 2003 for the CNES space project called PHARAO.

The DTT35XS off the shelves version is based on two pairs of APA35XS, Amplified Piezoelectric Actuators APA® displaying 35 µm of stroke each, arranged in cross configuration to allow an angular deflection of +/- 2 mrad around the X and Y axes. In order to achieve the two θx and θy angular deflections, each pair of APA35XS is electrically driven in push pull configuration and controlled in position by the standard CCBu20 controller box.

CTEC have been developing several customized versions of the DTT35XS together with CCBu20 for more than 10 years that are now widely used and embedded in Electro-Optic (EO) space and defence systems.

The features of the standard & custom designed versions of the DTT35XS provides the EO customers with a Compact, Dynamic and Precise solution to improve the performances of their embedded vision systems.

To name but a few applications are:

  • Micro-scanning, Dithering or Pixel shifting for image resolution enhancement of low cost detectors,
  • Optical image or line of sight (LOS) stabilization for anti shaking or anti blurring functions in order to obtain better image quality,
  • High precision Pointing ahead for free space optical (FSO) communication systems,
  • Fast steering mirror for Atmospheric disturbances compensation of astronomical imaging system (telescope) or high power laser beam system (DEW)

In the frame of ROXTAR, a MINALOGIC project dedicated to develop the next generation of XRay sensor for medical application, it has been spotted by our partner TRIXELL the interest to develop the capability of a blinded alignment between the imager and Xray emitter. The alignment function allows a better positioning of the imager relatively to emitter in order to:

  • Reduce the Xray dose exposure for any patient by avoiding multi shots to obtain one picture
  • Improving the quality of pictures

Cedrat Technologies (CTEC) designed and developed an accurate contactless magnetic long range (1.5 m) alignment function, based on magnetic technologies. This challenging technology where optical alignment is not allowed brings a positioning help to the medical operator, and hence achieve an alignment with a position resolution lower than 1mm and an angle resolution less than 0.1°.
A demonstrator has been developed integrating an user friendly Graphical User Interface, and shows the full capabilities of CTEC to specify and design from hardware to system level.

More information will be soon available.

MICA™: a new range of linear actuators

January 1st, 2017

French innovator CEDRAT TECHNOLOGIES launches MICA, its new range of linear actuators.

CEDRAT TECHNOLOGIES is unveiling its linear Moving Iron Controllable Actuator (MICA) product line onto the market, with associated drive electronics, in response to requirements in the industrial sector for highly reliable, long-life solutions.

The moving iron actuator designs created by CEDRAT TECHNOLOGIES are the highest performing in the sector compared to other classical magnetic actuators. The MICA™ actuator range is designed for high controllability, with higher force levels within more compact volumes and greater electrical efficiency. Their high efficiency results in heat dissipation through the very low Joule effect, together with easy and direct cooling on dedicated interfaces.

The new MICA200M is now available as a product. This linear actuator is issued from research work performed in the frame of the INTEFIX EC project and shows tremendous acceleration capabilities of 71 G in continuous mode and 132 G in peak mode. MICA200M complete the MICA (Moving Iron Controllable Actuator ) family.

MICA family actuators are well suited for ultra long lifetime applications, allowing achieving zero maintenance over several years of continuous operation. They are especially relevant for continuous operation with high level of integration inside production machines, and machining processes requiring vibration assistance, or precision control such as active chatter suppression.
