Digital speckle reduction in holograms - a comparison between methods Conference Paper uri icon


  • Digital holography, as any other coherent imaging modalities, is subject to speckle noise. Speckles may degrade significantly the image quality, therefore many optical and digital techniques were developed to suppress the speckles. In this paper we present a comparison between six digital speckle filtering techniques used for digital holography.
