Paper Abstract

In this paper, we present a novel adaptive optics testbed and its performance evaluation procedures. The testbed was built in the New Mexico State University (NMSU) Electro-optics Research Laboratory (EORL). NMSU's EORL adaptive optics testbed includes a tip-tilt error compensation system and a higher-order phase aberration compensation system. The tip-tilt error compensation was completed using a fast steering mirror with a quadrant cell detector. The higher-order phase aberration compensation was achieved using a 37-actuator deformable mirror and image sharpness with a stochastic parallel gradient descent algorithm (SPGDA). A metric optimization process was added in the SPGDA to fit an 8-bit deformable mirror control card. The system performance is evaluated using both static and dynamic phase aberration test conditions.
