Abstract
Registration of two types of digital holograms is considered: digital hyperspectral holograms and Denisyuk volume holograms (holograms in colliding beams). Hyperspectral holograms are considered as an analogue of thin holograms, in which zero order and a conjugate image are suppressed. Previously proposed principles are developed for the case of thick holograms in their digital representation. It is shown that the displacement of a scanning mirror in the process of hyperspectral holograms capturing is analogous to registering of the blackening function of layers of the volume hologram. The position of the mirror corresponds to the layers in a thick hologram, where the interference pattern is recorded in layers. An analogy is drawn between the restoration of a hologram by a light beam and its processing of its digital analog.
