Low voltage ferroelectric microdisplacement actuators are excellent candidates for use in zonal correction deformable mirrors (DMs) used in adaptive optical systems. Selection/specification is a critical process, however, since the device's electro-mechanical performance largely determines the mirror performance, and its electrical load characteristics strongly influence the cost of drive electronics. Several commercially available low voltage actuator devices were tested to establish a database for new DM designs. Both quasi-static and dynamic response characteristics were investigated. Test results are presented and conclusions are drawn concerning the merits of each device for typical deformable mirror applications.
