چکیده Holography is a 3D imaging method. In digital holography, like classical holography, speckle noise presents in reconstruction process and reduces the image quality. Thus, speckle noise reduction has strong effect on the image quality. Because of random distribution of speckle characteristics, it is too hard to eliminate them completely. Up to now some methods have been proposed for speckle noise reduction. In this work a method has been presented which is based on statistical property of speckle noise. By averaging multiple reconstructed images with different speckle noise patterns it has been reduced. These reconstructed images have been acquired by changing the sampling size in the hologram plane.
