Abstract

In this paper, we proposed a new method, controllable rectangle filter, to improve the resolution of reconstruction in multi-frame digital holography. In this method, the entire process needs only one hologram with multi-frame digital holographic interference and the different images' spectrum can be obtained separately without mutual influence. Therefore the size limiting of the recording objects is reduced and the frame amounts can be increased. Moreover, the nonessential information of zero-order and the conjugate image can be eliminated well, and the resolution of the reconstructed images is enhanced. Theoretical analysis and experimental results show that it is a realistic and practical approach.
