Abstract
Single crystal piezoelectric deformable mirrors with high actuator density, fine pitch, large stroke and no floating wires will be developed for future NASA science and communications applications. Single crystal piezoelectric DMs share the fine pitch with co-fired electrostrictive or ceramic piezoelectric DMs and MEMS DMs, but with large stroke at relatively low voltages (< 150 V) and with a broader operation temperature range (< 20 K - > 300K). Specifically, a 32x32 actuator array with stroke > 2 um, pitch of < 1mm and a 8x8 actuator array with stroke > 12 um, pitch of < 2mm will be developed for fine and coarse DMs. Actuator driving electronics will be scaled up to a multi-channel actuator driver and optimization of the design, facesheet mounting process and characterizations for deformable mirrors will be investigated.
