Abstract

One of principle difficulties in zonal wavefront reconstruction is computationally intensive. In this paper the method of wavelet decomposition is applied to the reconstruction matrix, then a threshold is added to the wavelet-coefficients matrix to remove the high resolution wavelet coefficients which can be ignored. The resulting matrix is sparse, leading the computational cost decreases greatly, so the computational speed increases. Theoretical analysis and computer simulation are made and expected result is got.
