The wavefront processing algorithm has an important influence on the working efficiency of the adaptive optics system.It is the premise for the restoration and correction of the wavefront aberration.Among them,the regional method,the mode method and the direct slope method are the classic algorithms for adaptive optics,which are the most widely used at home and abroad.In this paper,on the basis of summarizing the above three algorithms,two improved algorithms,fast iterative algorithm and Zernike mode fast algorithm,are introduced,and the advantages and disadvantages of various algorithms are compared and analyzed,and the improvement direction of future algorithms is expected.
