Abstract

The invention relates to a true three-dimensional image display system and a true three-dimensional image display method. The true three-dimensional image display system that is used for projecting K three-dimensional images to K view fields comprises at least one image source, an optical compression device, a holographic screen, and an optical scanning device. To be specific, the at least one image source is used for generating a plurality of holographic image light beams, wherein each holographic image light beam has image information of H-column pixels of the three-dimensional images and has N*K-column pixels. The optical compression device is used for compressing all the holographic image light beams to form narrow holographic image light beams; and each narrow holographic image light beam includes N-column view field image light beams and each column of view field image light beams include K columns of pixels. The holographic screen includes diffraction units that are used for receiving all the narrow holographic image light beams and diffracting the K columns of pixels of all columns of view field image light beams to the K view fields through all the imaging points. And the optical scanning device is used for scanning all the narrow holographic image light beams to the corresponding diffraction units. According to the invention, displaying of a true three-dimensional image can be realized and the resolution ratio is high.

Description

technical field [0001] The invention relates to image display technology, in particular to a true three-dimensional image display system and a true three-dimensional image display method. Background technique [0002] The so-called "true three-dimensional display" means that the relative positional relationship between the displayed three-dimensional objects is also truly reflected, forming a real three-dimensional space image, which has the surface characteristics of real physical depth and image quality, and the observer does not need any The auxiliary device can observe the displayed object arbitrarily from multiple directions, and perceive the most real and complete three-dimensional information. True 3D display technology fundamentally updates the concept of image display, makes the displayed image lifelike, provides complete psychological and physiological 3D perception information to the viewer, and provides a basis for understanding the spatial relationship between 3...
