Abstract

The invention provides a method and a system for generating holographic interference fringes. The method comprises: in the case of a digital image, generating a BMP grayscale bitmap and a BMP color bitmap of the digital image, generating a grayscale masking map by defining the corresponding relation between the angle range of the interference fringes and 256 grayscales, wherein the pixels of the grayscale masking map correspond to the pixels of the BMP grayscale bitmap and the BMP color bitmap one to one, and generating the holographic interference fringes of the digital image by using the BMP grayscale bitmap, the BMP color bitmap and the grayscale masking map. The method defines the corresponding relation between the angle range of the interference fringes and 256 grayscales so that the angle change of the interference fringes in the range of the interference fringes is much finer and subtler, thereby achieving a remarkable texture effect of a stereoscopic relievo.

Description

technical field [0001] The invention relates to the field of holographic imaging, and in particular to a method and system for generating holographic interference fringes. Background technique [0002] Holographic technology is a technology that uses the principle of interference and diffraction to record and reproduce the real three-dimensional image of an object. It can be divided into the following two processes: [0003] (1) Hologram generation process: Use the principle of interference to record the light wave information of the object, use a part of the laser to irradiate the object to form a diffuse object beam, and the other part of the laser is used as a reference beam to shoot on the holographic film to match the object. The beam superposition produces interference, which converts the phase and amplitude of each point on the object light wave into a spatially varying intensity, so that all information of the object light wave can be recorded by using the contrast a...
