Multidither Adaptive Algorithms.
Abstract
A 37-element beryllium deformable mirror has been built, characterized, and incorporated into a Coherent Optical Adaptive Technology (COAT) system. Individual actuator deformation sensitivities of 0.2 micrometer/150 V have been measured. Mirror resonance data has been obtained indicating usable frequency ranges up to 30 to 40 kHz. Strehl ratios approaching 80% have been measured for system defocus with COAT-off to COAT-on peak irradiance of 10. (Author)
