Demokit P-FSM150S

This new demokit has been created to show the implementation of our Piezo Fast Steering Mirror (P-FSM). This kit aim to demonstrate CTEC’s capability in developing compact mechanisms and driving electronics. It utilizes a P-FSM150S, a laser, and mirrors to amplify the laser deflection, making it visible on a screen within a confined space.

This FSM has been developed for the New-Space market with an approach focused on standardization and cost reduction. It can perform pointing and stabilization functions and are the result of 25 years of space heritage. 

The electronic used is the Compact Controller Board CCBu20 which is an embedded all-in-one controller designed for piezo actuators. It includes everything necessary to drive and control a 2-axis piezo mechanism in a closed loop. As a standard feature, its integrated dual-channel SG conditioner enables the reading of the position of the two axes of the mechanism.

Both axes of the FSM are actuated at different frequencies, creating a visual effect of a rotating rosette due to retinal persistence.
