Calibration of Hartmann-Shack sensor for measurement of wavefront in prototype system

In high power solid-state laser driver, the calibration of reference wavefront is a key technique in the use of adaptive optics system. Based on the optical character of certain laser prototype system, two calibration methods are researched contrastively. Main factors affecting the accuracy of calibration are obtained. Based on the reference wavefront of the more accurate calibration result, the validity of the result is proved by far-field changing before and after AO correction. The result has been successfully used in AO system wavefront correction experiment of this prototype system.
