Abstract

Effective application of membrane deformable mirrors requires understanding of the operating characteristics of these devices. Using custom developed hardware and software tools, we were able to quantify the temporal and spatial response characteristics of a membrane deformable mirror. Temporal characteristics were analyzed using a frequency sweep stimulus while measuring the DM response on a feedback photodiode. Spatial characteristics of the DM were analyzed in terms of its ability to reproduce Zernike polynomials of increasing order using a variety of actuator patterns. We present here both the techniques for performing these measurements and the results from simulation and the laboratory.
