    Abstract:

    According to the Collins formula and its inverse diffraction computation, this paper presents an algorithm for reconstructing the object wavefront of a numerical holograph. To improve the quality of wavefront reconstruction, a technique of eliminating the zero-order diffraction light is introduced, which is achieved by subtraction of two intensities of the interference patterns. The computer simulation and image processing show that the method of eliminating the zero-order diffraction beam can be applied to the wavefront reconstruction of inverse diffraction computation.
