High-resolution holographic three-dimensional display device and high-resolution holographic three-dimensional display method on basis of multilayer spatial light modulator

Abstract

The invention discloses a high-resolution holographic three-dimensional display device on the basis of multilayer spatial light modulators. The high-resolution holographic three-dimensional display device comprises a coherent light source, a beam expanding and collimating system, a spatial light modulator group, an image transmission module and a computer. The spatial light modulator group comprises N spatial light modulators arranged in parallel. The invention further discloses a holographic three-dimensional display method on the basis of the multilayer spatial light modulator. The multiple layers of spatial light modulators are arrayed from front to back, each layer of light modulators codes and modulates light beams incident thereon in a holographic manner according to coding images loaded by the computer, a high-resolution holographic three-dimensional light field of real space is reproduced, the observation range of holographic display is expanded, displayed images can be simultaneously viewed by various people with naked eyes at various viewing angles, discomfort of the observers generated in a three-dimensional displayed image viewing process is eliminated, and the natural physiological and psychological habits in aspects of visual observation and depth perception of human being are automatically conformed.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional display, and in particular relates to a high-resolution holographic three-dimensional display device and method based on a multilayer spatial light modulator. Background technique [0002] Vision is the main way for humans to understand the world and nature. About 80% of the information obtained by humans comes from vision. For a long time, the main means of expressing visual information is still two-dimensional. Traditional two-dimensional display technology loses the depth information of the real physical world, seriously hinders human perception of the objective world, and affects the accuracy, depth, speed and accuracy of human information acquisition, processing, transmission, human-computer interaction and decision-making. efficiency. Human beings are born spatial thinkers, hoping to obtain 3D image information intuitively. Therefore, how to realize the three-dimensional display ...

AI Technical Summary

Problems solved by technology

[0006] At present, static holographic display technology has been widely used, while dynamic holographic display technology requires a high-resolution information storage medium (high-resolution spatial light modulator), but due to the comparison of the pixel size of the existing spatial light modulator The large resolution is still relatively low, so the diffraction angle is relatively small, and the size of the diffraction angle limits the observable field of view
