%X Using spherical wave as the reconstructive wave,the convolution reconstruction process of object plane optic wave field was studied theoretically when the object projection size was much larger than CCD array size and the object surface detected by digital holography was regarded as scattering surface.The relationship between magnification of the reconstructed object field and the reconstruction parameters was also derived.The other two methods of convolution reconstruction were introduced briefly,which were expanding CCD plane with zero-padding and combination of local reconstruction object.These three methods were experimentally compared with.And the results show that the method using spherical wave as the reconstructive wave is better than the rest.
