Technical Field

[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 the real three-dimensional image of an object. Holographic projection technology can not only produce three-dimensional aerial illusions, but also enable the illusions to interact with performers to complete the performance together, producing a shocking performance effect. At present, holographic projection devices generally have a holographic projection screen and a holographic projector, but the projection screen in the existing holographic projection device cannot be adjusted in height according to the needs of the user, thereby reducing the flexibility and adjustability of the holographic projection device. After the device is moved to the specified position, the wheels cannot be effectively raised and lowered, which may cause the device to be unstable during operation and inconvenient to store, increasing the storage space; therefore, we propose a holographic projection device with an adjustable projection screen to solve this problem.
