How the nonlinearity of synthesized holograms affects their imaging properties

摘要

This paper discusses the main features of image formation by means of synthesized holograms, caused by the inherent nonlinearity of the mathematical description of the holographic field. Special attention is paid to discrete halftone and binary holograms, which are a limiting case of nonlinear holograms. Recommendations are given for choosing synthesis conditions that make it possible to obtain a reconstructed image identical to the object with the maximum number of allowable threshold-processing levels.
