Problems solved by technology

But at this stage, due to the lack of 3D film sources that can be used by it, it is difficult to bring out its display advantages
Moreover, the structural limitations of the display system are relatively large. In many application scenarios, it is impossible to provide enough system layout space for it. The system is complex and the cost is high.
[0005] At the same time, the optical parameter settings of the above-mentioned display system need to be carefully designed to ensure the ideal display effect and the reliability of the display system, otherwise the display system may not be able to achieve the ideal display effect or fail to guarantee reliability due to inappropriate display parameters

Abstract

The invention relates to the field of 3D display, and discloses a folded light path geometric holographic display system, which comprises at least one projector, a transmission type geometric holographic screen, a support structure, a controller and at least one light path folded lens group, the light path folding mirror group at least comprises a plane mirror with a reflection function, and is used for changing a propagation path of light projected by the projector; the number of viewpoints of the folded light path geometric holographic display system is n; the mean value of the diameters ofthe light-transmitting parts of the lenses on the outermost side of the projector is D decimeters; the mean value of the projection light source power of the projector is P watt; by introducing the light path folding lens group capable of changing the propagation path of the projection light of the projector, the light path is flexibly converted and folded, the space can be reasonably utilized, the space occupancy of the whole display system is reduced, and the layout flexibility of the display system is effectively improved.

Description

technical field [0001] The invention relates to the field of 3D display, in particular to a folded optical path geometric holographic display system. Background technique [0002] Compared with traditional 2D display technology, 3D display technology can provide depth information, thereby displaying more visual information and making the displayed image more reductive. Therefore, 3D display technology is a very popular technology in academic research at present. Among them, the 3D display scheme based on holographic technology can restore the light field distribution of the real physical world in principle, thereby completely restoring all the optical characteristics of the 3D scene. The traditional holographic display technology uses the fluctuation characteristics of light to record the light intensity information and phase information of the scene at the same time, so as to realize the recording of the light intensity, color and depth of field of the scene. However, thi...
