摘要
Large space-based optical systems are expected to produce optical beams with large wavefront phase aberrations due to their size, weight limitations, optical misaligments and primary mirror imperfections. The present invention combines a phase diversity wavefront sensor with a real- time programmable two-dimensional array of liquid crystal variable retarders for wavefront correction.
