Title: Study on inverse calculation of fresnel diffraction
Abstract: The inverse calculation for the phase of optical wave field of Fresnel diffraction is a significant but difficult work.In this paper,we presented the method that implement inverse calculation of Fresnel diffraction.We also research the reconstruction of optical field of circular aperture in Fresnel diffraction region by using the theory and technology of digital holography as well as diffraction calculation and the algorithm of phase un-wrap.Finally,we complete the work of computer simulation and experimental calculation,which calculated optical wave field distribution of circular aperture diffraction using inverse calculation of diffraction.The results of experimental match well with simulated.
