Abstract

Digital holography is a popular technique for investigation of changes of objects parameters: shape, density, temperature, and etc. Speckle noise, twin image, zero order, digital camera's temporal noise and fixed pattern noise (FPN) limit quality of images reconstructed from digital holograms. FPN is the only problem that actually was not researched. In this work effect of digital camera's FPN on reconstructed images is investigated. Characteristics of CCD and CMOS cameras of different types were used: scientific camera, video-surveillance camera, and others. Results of numerical reconstructions from holograms with different FPN are presented. Signal-to-noise ratios are obtained for the reconstructed images.
