Digital Recording and Numerical Reconstruction of Holograms

Leonid Yaroslavsky and Jaakko Astola


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
