Piezoelectric Single Crystal High Density Actuator Deformable Mirror

Conventional adaptive optics systems employed to compensate wavefront errors introduced by atmospheric index of refraction variations are limited to correcting relatively small turbulence errors due to the physical limitations of the corrective devicesavailable. A high density deformable mirror actuator array using piezoelectric single crystal MPB PMN-PT would provide far greater stroke to correct large turbulence errors at high spatial frequencies. In addition, it would be applicable to errorcorrection in a host of optical communities who have a direct and current need for such a device. The objective of this Phase I program is the development of MPB PMN-PT single crystal high density deformable mirror actuator array prototype to demonstratehigher authority actuation response, dimensional stability, and wavefront control.Higher Amplitude Error Correction in Satellite Surveillance SystemsEnhanced Laser Focusing over Longer DistancesAdditional Agility in TelecommunicationsHigher Sensitivity Sonar TransducersImproved Ultrasonic Imaging
