Abstract

Characterizing the fundamental response and operational parameters of a deformable mirror is a critical first step in the design of an adaptive optics system. This paper describes the characterization of the influence function and training of a piezoelectric deformable mirror (PDM) at 632 nm. We scale the results to 1550 nm for low to mid order aberration correction for free space laser communications applications in the Short Wave Infrared (SWIR). A modified Twyman-Green interferometer was used to measure the influence functions and to characterize the mirror. The data was analyzed using commercial and customized software.
