However, the existing liquid crystal displays are mainly used for two-dimensional flat display. Even small-sized projector liquid crystal panels have pixel sizes on the order of ten microns. Compared with visible light wavelengths, their resolution is still very low, and they cannot be used to replace holograms. Film for large field of view, high-quality 3D holographic display

Embodiment Construction

[0041] The terms used in the present invention are explained below.

[0042] 1. The amplitude and phase adjuster array adjusts the amplitude and phase of the incident light point by point, similar to a spatial light adjuster. However, one spatial light adjuster can generally only adjust the phase or amplitude, so the array of amplitude and phase adjusters in the present invention is equivalent to the combination of two spatial light adjusters, and the pixels of the two spatial light adjusters are aligned with each other. One of the spatial light adjusters is mainly used to adjust the phase, and the other is mainly used to adjust the amplitude. An amplitude and phase adjuster in the amplitude and phase adjuster array is equivalent to a pair of mutually coupled pairs of two spatial light adjusters. pixels.

[0043] 2. Liquid crystal panel refers to a liquid crystal spatial light modulator with many pixels. Its structure is similar to that of an ordinary nematic liquid crystal d...

Abstract

The invention discloses a three-dimensional display device based on a random constructive interference principle, which adopts an amplitude and phase regulator array to regulate the amplitude and phase of incident laser and the converging function of a reflective or transmissive holographic optical element or binary optical element or tilted microlens to generate a coherent sub light source array of which the position is random, so that coherent sub light sources generate constructive interference to form a three-dimensional image. The device adopts a gray scale liquid crystal panel as well as the partitioned lighting by red, green and blue lasers to realize real-time color three-dimensional display, can be widely used in fields of three-dimensional display in computers and televisions, three-dimensional man-machine exchange, robot vision and the like.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional imaging, and more specifically relates to a three-dimensional display device based on the principle of stochastic constructive interference, which is especially suitable for computer and TV display screens, intelligent man-machine exchange, robot vision, etc., and can be widely used in teaching, Scientific research, entertainment, advertising and other fields. Background technique [0002] In the past 10 to 20 years, liquid crystal display technology has been developed rapidly, from projected liquid crystal display panels of a few tenths of inches to flat-panel liquid crystal displays of tens of inches have been commercialized. However, the existing liquid crystal displays are mainly used for two-dimensional flat display. Even small-sized projector liquid crystal panels have pixel sizes on the order of ten microns. Compared with visible light wavelengths, their resolution is stil...
