Abstract: Digital holograms which are recorded in the CCD sensors is subjected to numerical reconstruction for calculation of amplitude and phase using numerical reconstruction algorithms. This reconstruction process offers high flexibility and provides new possibilities of exploitation in domains like pattern recognition, 3D microscopy, encryption etc. In this paper,a comparative analysis of different holography reconstruction methods is presented.

Abstract: Speed up of transmission of information about 3D-scenes and reducing of archival memory size required to store it, are important for surveillance systems and biomedical applications. For solution of these tasks, methods of digital hologram compression are used. In the paper the most popular methods are considered. They can be divided into three groups: methods based on images and video compression standards, scalar methods and vector methods. Advantages and drawbacks of the methods are considered.

Abstract: In this paper, we consider the opposite problem, namely, using of color digital holograms simultaneously recorded on several wavelengths for the reconstruction of monochromatic images. Special feature of the procedure of monochromatic image reconstruction from the color hologram is the necessity of extracting information from separate spectral channels with a corresponding overlaying of obtained images to avoid mismatching of their spatial position caused by dependence of methods of numerical reconstruction from the laser wavelength.
