| Abstract: | The separation of the reconstructed images in digital holography is analyzed firstly.Then the difference between the reconstructing condition of the digital holography and that of the classical holography is pointed out. At last, the geometrical arrangement of the optical components is studied, and a spacial frequency filtering method is introduced to partly avoid the overlapping. Some verified experimental results are given. |
