2. Overview of holographic projection technology
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.
Its basic principle is to illuminate the object with a beam of light (object light) and superimpose the reflected light (or transmitted light) of the object with another beam of reference light (usually a plane wave) on the recording medium to produce an interference pattern, namely a hologram.
When the hologram is illuminated with appropriate, coherent light, the three-dimensional image of the original object can be reproduced through the diffraction effect.

By building a holographic projection system, users can be provided with an immersive virtual reality experience. For example, in the field of games, holographic projection technology can create realistic game scenes and characters, and improve the fun and attractiveness of games.
- Augmented Reality (AR):
In the field of augmented reality, holographic projection technology can combine virtual images with real environments to provide users with richer information display and interaction methods.
For example, in the guide system, holographic projection technology can display virtual reconstruction models of historical relics, allowing users to understand historical culture more intuitively.
- 舞台表演：
The application of holographic projection technology in the field of stage performances has been quite mature. Through holographic projection technology, a fantastic stage effect can be created, bringing a shocking audio-visual feast to the audience.
For example, in concerts, holographic projection technology can be combined with music to present colorful visual effects; in theater performances, holographic projection technology can assist actors in their performances and enhance the appeal of the plot.
