Paper Abstract

In this study, we demonstrate reduction of speckle noises of digital holography using speckle correlation properties in the longitudinal direction. In this method, it is assumed that digital holograms of diffuse objects are recorded on an image sensor. Using multiple holograms recorded by moving the image sensor to the longitudinal direction, the speckle noise of a reconstructed image is reduced and therefore the image quality is improved by the proposed method.
