Abstract
To meet needs in air, space, defence & other embedded or demanding applications CEDRAT TECHNOLOGIES (CTEC) has developed for more than 20 years Fast Steering Mirrors (FSM). Typical applications are for example Lidar, free space optical communication (FSO) and Laser interferometry. As the specifications met in these applications can vary, CTEC has designed and patented different actuation technologies:
-
FSM based on Amplified Piezo Actuators APA®, as for PHARAO, ATLID, PSYCHE missions, and for future FSO space constellations as well as other large FSM for space & instrumentation as ESO ELT.
-
FSM based on Magnetic Actuation, as being developed for FSO and CO-OP optical communication toward Geosat.
-
FSM based on Stepping Piezo Actuators, as for IASI-NG for METOP-SG, as well as other piezomotor-based FSM.
The presentation describes the working principle, design and performance of these different actuation concepts.
