Liquid Crystal-Spatial Light Modulators(LC-SLM)control the optical path by modulating the refractive index of liq-uid crystal,and play an important role in adaptive optics.This paper sorts out the development status of LC-SLM at home and abroad,and introduces the working principle and phase calibration principle of LC-SLM in detail.Aiming at the application of LC-SLM in adaptive optics,the research status of key technologies of LC-SLM at home and abroad is discussed.The experi-mental research in this field of Xi'an University of Technology is analyzed and summarized.Finally,the application status of LC-SLM is prospected.
