Optical reconstruction of computer-generated holograms 3D scenes via spatial light modulators

Abstract

This work presents the optical reconstruction of computer-generated holograms (CGHs) 3D scenes via spatial light modulators (SLMs). Holography is an optical technique that allows the recording and reconstruction of images of 3D objects, as a hologram carries the intensity and phase information about the object. With the evolution of data storage and processing in computers, the viability of generating holograms by computers has increased. Currently the experimental implementation of CGHs (Computer-Generated Holograms) is done through new optoelectronic devices such as SLMs (Spatial Light Modulators) and high-resolution CCDs cameras, in addition to new photosensitive materials, allowing the optical recording and reconstruction of 3D images and special optical beams. Therefore, presented here with good results are CGHs numerical construction (recording) of images both static and dynamic, 2D and 3D, and its reconstruction (reproduction) using optical SLMs devices to obtain 3D images and static and dynamic scenes.
