Abstract

In digital holography, like classical holography, speckle noise appears in reconstructed images and reduces the image quality. Because of statistical properties of speckles, size and intensity, their intensity distribution strongly depends on the locations where they are formed. In this work a method is presented to reduce the speckle noise based on these properties by reconstruction several images in various locations and then averaging these images. Experimental results verify effectiveness of this technique.
