Integral computer-generated hologram via a modified Gerchberg-Saxton algorithm

Abstract

An integral computer-generated hologram, which modulates the phase function of an object based on a modified Gerchberg-Saxton algorithm and compiles a digital cryptographic diagram with phase synthesis, is proposed in this study. When the diagram completes position demultiplexing decipherment, multi-angle elemental images can be reconstructed. Furthermore, an integral CGH with a depth of 225 mm and a visual angle of +/- 11 degrees is projected through the lens array.
