%X A method of wavefront data fitting using Zernike polynomials is presented.Generation of orthogonal polynomials on a discrete set of data points is given and procedures of computing wavefront coefficients are described.It is mainly used in the cases of low modulation,speckle,noise or dust points.Through the establishment of a certain threshold,a mask is set up on error points.The measurement accuracy is inproved further.
