Problems solved by technology
However, due to the high cost of display screens and related control circuits, it seriously restricts the popularization of holographic projection technology in daily life.
[0004] Moreover, in some application scenarios, only a very simple dynamic image needs to be projected, such as an image of an object or a sign that is constantly rotating. If the existing holographic projection equipment is used, it will be a bit overkill and costly.

Embodiment Construction
[0024] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0025] like figure 2 and image 3 As shown, an image disk that can be used for holographic projection mainly includes an image disk body 1. The image disk body 1 preferably adopts a disc-shaped structure, which has an optimal structure and takes up less space. The image disk body 1 can also be a square disk. Shaped structures and polygonal disk structures and similar structures. There are N sets of projection source images on the image disc body 1, and each set of projection source images is composed of four individual images 1a distributed symmetrically across the cross, that is, in each set of projection source images, the four individual images 1a are distributed at intervals of 90° On the image disk body 1. Overall, 4N single images 1a are evenly distributed in a ring shape on the image disk body 1 , the part of the image disk body 1 with the single i...

The invention discloses an image disc capable of being used for holographic projection, which comprises an image disc body, N groups of projection source images are arranged on the image disc body, and each group of projection source images consists of four single images which are symmetrically distributed in a cross shape. The invention further discloses a high-cost-performance holographic projection display device which comprises the image disc, an imaging lens set, a driving device and four light sources, and the four light sources correspond to the four imaging lenses in a one-to-one mode.According to the technical scheme, the image disc capable of being used for holographic projection and the high-cost-performance holographic projection display device are novel in structure, ingenious in design, easy to implement, capable of generating simple dynamic three-dimensional images capable of being continuously and circularly played, capable of being matched with man-machine interactionand better in interaction effect; the image disc is simple, stable, reliable, durable and low in cost, and has extremely high economic and market values.
Description
technical field [0001] The invention relates to the field of projection technology, in particular to an image disk capable of holographic projection and a cost-effective holographic projection display device. Background technique [0002] Traditional human-computer interaction interfaces are mainly two-dimensional patterns or two-dimensional luminous icons, and there are also dynamic two-dimensional displays. With the improvement of living standards and people's higher requirements for intelligence and interface friendliness, traditional two-dimensional methods cannot meet. With the advancement of science and technology and the development of economy and society, holographic projection technology has gradually been applied to people's daily life, which can provide a better human-computer interaction interface. Holographic projection technology is a kind of 3D technology, which refers to the technology of recording and reproducing the real three-dimensional image of an objec...
