Description

technical field [0001] The invention relates to a position mismatch measurement and alignment system of a wavefront sensor and a wavefront corrector in an adaptive optics system. Background technique [0002] In the adaptive optics system, the positions of the wavefront corrector and the wavefront sensor need to meet the optical correspondence, and the wavefront sensor and the wavefront corrector are two independent devices, and the relative translation and rotation of the two will vary to varying degrees. Changing this relationship affects the wavefront correction capability of the adaptive optics system. In the actual working process of the adaptive optics system, once the two positions are mismatched, we will adjust it manually. However, this alignment method lacks accurate alignment basis, and the alignment accuracy cannot be guaranteed . At the same time, the traditional alignment method also limits the application field and the expansion of the application scale of a...
