Problems solved by technology
[0002] Holographic projection technology, also known as virtual imaging technology, is a technology that uses the principles of interference and diffraction to record and reproduce real three-dimensional images of objects. The holographic projection screen of some holographic projection equipment is generally placed on a fixed table, and the adjustment of the rotation angle and height cannot be adjusted. Therefore, a simple structure is developed, which can rotate and adjust the height of the holographic projection screen, which can improve The adjustment effect is good, and the holographic projection device that improves the viewing effect is very necessary
