Embodiment Construction

[0102] figure 1 A schematic block diagram of a 3D holographic display (3D holographic display) system 100 according to an embodiment of the present invention is shown, which is an adjustable multi-focus system. In this embodiment, a stereoscopic holographic display system 100 (hereinafter referred to as a display system), such as a head-up display or a head-mounted display, may include a projector 11, such as a spatial light modulator, SLM), which is used to spatially modulate the light beam to generate an image. In one embodiment, the spatial light modulator may comprise single crystal silicon liquid crystal on silicon (LCOS).

[0103] The display system 100 of the present embodiment may include a holographic processor 12, such as an image processor, for performing a holographic method on the image generated by the projector 11, the details of which will be described in the following sections. The display system 100 of the present embodiment may include a storage device 13,...

Abstract

The invention discloses a three-dimensional holographic display system, which comprises a projector, which spatially modulates a light beam to generate an image; a holographic processor, which executes a holographic method on the image generated by the projector; and a storage device, which stores the holographic image. The holographic data generated by the processor during the execution of the holographic method. The holographic processor adaptively displaces the amplitude of the light field according to the salience of individual regions of the image.

Description

Background technique [0001] A hologram is a stereoscopic image that can be seen with the eyes, and a holography is a technique that produces a hologram. Generally speaking, a hologram is a record of a light field, which is a vector function that describes the amount of light flowing in all directions at each point in space. [0002] A head-up display (HUD) is a transparent display that can display data without the user leaving the general line of sight. Holographic technology can be used as a projector for head-up displays to display stereoscopic images. [0003] Computer-generated hologram (CGH) algorithms can be divided into two categories: direct methods and inverse methods. Direct methods, such as direct method (DS), simulated annealing (SA), and genetic algorithm (GA), calculate each pixel and thus achieve high accuracy, but require longer computation time . On the other hand, inverse methods, such as the Gerchberg-Saxton algorithm and the iterative Fourier transform ...
