title = "Reduction of speckle noise in digital holography by multiple holograms",
abstract = "In this paper, we introduce and demonstrate a new method of reducing speckle noise by multiply holograms. It can utilize both the phase and amplitude information of the object wave-front. In the superposition process, the phase surfaces with high signal to noise ratio in the different phase images have been appropriately weighted according to reconstructed intensity image. We show a theoretical justification of the procedure and experimentally-obtained results of a USAF-1951 resolution test target, both of which demonstrate that the proposed method could reduce the speckle noise effectively, and improve the resolution of reconstructed image. 2009 SPIE.",
