Digital recording and numerical reconstruction of holograms is one of the main tasks of digital holography with numerous applications. This chapter exposes off-axis and on-axis methods of hologram digital recording, introduces the notion of the point-spread function of numerical reconstruction of hologram, which is the main metrological characteristics of the process, presents results of evaluation of point-spread functions of numerical reconstruction of Fourier and Fresnel holograms and discusses zones of applicability of different reconstruction algorithms
