Abstract

One of the most common problems in classical and digital holography is presence of speckle in reconstruction process. Some methods have been predicted for speckle reduction. Speckles have statistical distribution in size and intensity. Thus, complete elimination of them is impossible. But one can use this statistical characters for reduction its effects. In this paper a method is proposed for reduction of speckle effect by recording a hologram for different illumination directions, but simultaneous, of the object. Experimental results verify effectiveness of this technique.
