A kind of adaptive optical principle correction system based on compound liquid crystal spatial light modulator (LC-SLM) is designed and built. One spatial light modulator is used for wavefront simulation and the other for wavefront correction. The Zygo interferometer is used to detect the distorted wavefront. The conjugate wavefront of the distorted wavefront is obtained by the program calculation, and the corresponding gray image is generated, which is loaded into the LC-SLM to compensate the distortion wavefront, and the static wavefront correction is realized. The calculated Stell-ratio increases from 0.3795 before correction to 0.8268, and the mean value of the ring girth gray increases from 382.75 before correction to 1164.5, and the luminance aggregation of the spot is obviously improved. Compared with the pure phase space light modulator, the composite space light modulator saves costs and is suitable for laboratory batch use.
