Embodiment Construction

[0011] The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0012] This example provides

[0013] A calculation hologram production and reproduction method includes the following four steps: sampling, calculation, encoding, storage and reproduction of object light information.

[0014] 1) Sampling of object light information, obtaining the value of the object or wave front at discrete sample points, that is, converting the continuous function of the wave front information into a discrete function, directly inputting the wave function of the simulated object into the computer or using methods such as shoot...

Abstract

The invention discloses a method for making and reproducing a computer-generated hologram, which relates to the technical field of holographic image processing. The method includes the following foursteps: object light information sampling, computing, coding, and storage and reproduction. Through the method for making and reproducing a computer-generated hologram provided by the invention, the record of reproduced waste information can be reduced under the condition that reproduced effective information is unchanged, the amount of computation of a hologram can be reduced, and the generation speed of a computer-generated hologram can be improved.

Description

technical field [0001] The invention relates to the technical field of holographic image processing, in particular to a method for making and reproducing a calculated hologram. Background technique [0002] Computational hologram is a widely used form of holography. Its recording optical path is similar to that of traditional optical holography, but the recording device of hologram uses CCD camera or CMOS camera. Computational holograms can also be obtained from ordinary images by simulating the optical interference process. The reproduced image can be digitally reproduced using a computer, or the hologram can be printed on a transparent material after necessary processing, and then optically reproduced. In the prior art, the image reconstruction effect of the holographic image is poor and other defects. Contents of the invention [0003] The method for making and reproducing a computational hologram proposed by the present invention has the advantage of realizing a good...
