【Abstract】 In the study of color digital holography,using the spherical wave as the reconstruction wave,the wave-front reconstruction with the angular spectrum diffraction formula is an effective approach. However,this method is usually accompanied by intense zero-order diffraction interruption. In this paper,based on the theoretical analysis,an important modification of the wave-front reconstruction process has been made. The color digital holography experiment result demonstrated that the quality of reconstructed color image has been improved remarkably with this modified method.更多还原
