Description

Technical Field

[0001] The present invention relates to the technical field of multi-dimensional holographic projection, and in particular to a multi-dimensional holographic projection system and equipment. Background Art

[0002] Multi-dimensional holographic projection technology is an advanced display technology. It can present three-dimensional images on a two-dimensional plane through optical principles and projection technology, or more precisely, it can create a three-dimensional image in space. The core principle of multi-dimensional holographic projection technology is to record and reproduce the holographic image of an object. A holographic image is an interference image that records the distribution of the light field of an object, which captures the phase and amplitude information of the object. Specifically: Recording process: When recording a holographic image, the light source is divided into two beams of light by a beam splitter. One beam is directly irradiated onto the photosensitive medium as a reference light; the other beam passes through the object and then irradiates the photosensitive medium as the object light. When the two beams of light intersect, interference occurs, forming an interference pattern, namely a holographic image. This holographic image records all the information of the object's light wave, including amplitude, phase, and frequency. Reproduction process: When reproducing a holographic image, the same light source as that used when recording is used to illuminate the holographic image. After interference, light will form a light field that is very similar to the original light field of the object, thus producing a realistic three-dimensional effect. However, in the existing multi-dimensional holographic projection system, it is difficult to ensure the privacy of viewing the holographic projection when it is needed to control the viewing privacy of the holographic projection. There is no personalized recommendation function for the content when users watch the holographic projection, which affects the viewing effect of different users on the holographic projection display.
