Abstract

The method and corresponding optical scheme for the registration and reconstruction of digital volume holograms are considered. It is shown that a set of digital holograms recorded with a scanning reference beam makes it possible to reconstruct the complex amplitude of the object field. The proposed method for registering digital holograms is considered a digital analog of Denisyuk’s holography. In particular, a condition is obtained connecting the number of steps (number of holograms) with the quantity of the phase step, when the background and conjugate image are eliminated after the reconstruction procedure of an object field according to the suggested algorithm. Experimental results are presented validating the proposed approach.
