Abstract:

We present a closed-loop adaptive optics system based on a holographic sensing method. The system uses a multiplex holographic recording of the response functions of each actuator in a deformable mirror. By comparing the output intensity measured in a pair of each photodiodes, the absolute phase can be measured in a pair of each actuator location. From this a feedback correction signal applied to the input beam without need for a computer.
