Paper Abstract

We present results from a fast holographic adaptive laser optics system (HALOS) incorporating a MEMS-based deformable mirror and an off-the-shelf, photon counting avalanche photodiode array. A simple digital circuit has been constructed to provide autonomous control and the entire system is no larger than a shoebox. Our results demonstrate that this device is largely insensitive to obscuration and in principle can run as fast with one actuator as with one million. We further show how HALOS can be used in image correction, laser beam projection as well as phased-array beam combination.
