Abstract

The space adaptive optics system used for space remote sensing system to improve the image quality will face the challenge from the wider field of view. In this paper, the SPGD algorithm is present to realize the wavefront sensorless adaptive optics correction for a wide field of view optics system. Giving the traditional TMA optics system as the example, the image quality of different field of view is analyzed when there are some different surface errors in the optics system. The gradient evaluation method and convergence of SPGD is analyzed in detail. The issue of parameter such as the gain and step selection for SPGD is discussed. Computer simulation of a remote sensing AO system based on SPGD is studied. And the results show that wavefront sensorless wide field of view adaptive optics correction based SPGD algorithm for the segmented primary mirror system is acceptable, and the wavefront error is within 1/10λrms.
