DTT35XS_FSM

The Double Tip Tilt (DTT35XS) from Cedrat Technologies is a piezo point ahead mechanism/fast steering mirror platform initially developed in 2003 for the CNES Pharao space project. The DTT35XS off-the-shelf version is based on two pairs of APA35XS, amplified piezoelectric actuators displaying 35µm of stroke each, arranged in cross configuration to allow an angular deflection of +/- 2 mrad around the X and Y axis. In order to achieve the two θx and θy angular deflections, each pair of APA35XS is electrically driven in a push/pull configuration and controlled in position by the standard CCBu20 controller box.

Cedrat has been developing several customised versions of the DTT35XS, together with CCBu20 for more than 10 years and these are now widely used and embedded in electro-optic (EO) space and defence systems.

The features of the standard and custom designed versions of the DTT35XS provide the EO customers with a compact, dynamic and precise product to improve the performance of embedded vision systems.

Applications include:

Micro-scanning, dithering or pixel shifting for image resolution enhancement of low-cost detectors,

Optical image or line of sight (LOS) stabilisation 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 an astronomical imaging system (telescope) or a high-power laser beam system (DEW).
