Abstract
In this paper, a diverging spherical beam goes through the object field and the part of the beam diffracted by the objects and arriving at the recording surface is considered the object beam, while the beam arriving without any distortion is considered the reference beam. The superposition of the two beams creates an interference pattern on the CCD sensor. The magnification image can be obtained by two methods based on convolution method and Fresnel method. The relationship between the quality of holograms and some parameters was obtained by comparing the images of reconstruction at different distances. The convolution method is better than the Fresnel method. The results show that the digital holography using spherical wave can work well.
