Embodiment Construction

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details. In other instances, some technical features known in the art have not been described in order to avoid obscuring the present invention.

[0029] The invention discloses an algorithm for computational holography, which specifically includes: collecting object light information, processing the object light information, expressing the light field distribution on the holographic plane with the transmittance of the computational hologram according to an encoding method, and Recording storage and reproduction of holograms.

[0030] Collection of object light information: For objects that actually exist, you can directly use scanners or digital cameras for data collection, and for objects that do ...

Abstract

The invention discloses an algorithm for computational holography and belongs to the technical field of projection. The algorithm comprises steps that S1, the object and light information is collected; S2, the object and light information is processed; S3, light field distribution on a holographic plane is expressed by computational hologram transmittance based on the encoding method; and S4, thehologram is recorded, stored and reproduced. The algorithm is advantaged in that the computational holography can be done without relying on real objects and only needs to obtain specific mathematicaldescription of object waves, so the computational hologram can be obtained through utilizing a computer and output equipment, and making and synthesizing 3D simulation book holograms can be more convenient.

Description

technical field [0001] The invention belongs to the technical field of projection, and in particular relates to an algorithm for computational holography. Background technique [0002] The holographic projection technology can realize the full three-dimensionalization of the projected image. The holographic projection technology has attracted people's attention with a new perspective. This time, we used this new technology in the book display. The expected scene is to suspend the three-dimensional book picture in the air, and the effect has a strong sense of depth, and it is both true and false, which makes people feel very strange. Observers can get the appearance of books in different directions by observing them from different perspectives. [0003] Holography has formed different achievements in different stages of development. It has many classifications, including traditional optical holography, digital holography, and computational holography. Computational holograp...
