The definition of holographic projection
The gauze screen projection , which is generally not used as a fixing device for performance venues, is a translucent curtain made of thin cotton cloth or chemical fiber with reticulated holes. It is widely used for the holographic projection or gauze projection. Gauze as a special screen is most applied for the live holographic 3D digital projection, interactive holograms, and other types of holographic displays.
Gauze holographic screen can be extremely fine barbed wire mesh, can also be not easy to be seen by the naked eye of meticulous gauze and so on. Different materials and colors also make them different in effect, which based on the effect of the holographic displays.

With its characteristics of light transmittance, lightness and high degree of color reduction, gauze screen can be described as a great display in the creative presentation of multimedia dance images, which not only helps dance images to create virtual and realistic visual scenes, but also expands the level of stage space. It strengthens the interaction between the actors and the images in the performance and adds a lot of color to the whole performance.
The application of holographic projection
1. Holographic projection to create virtual realistic scene
Because of the light transmittance of the gauze, the transparency of the screen can be changed by adjusting the projection point of the light source to form a secondary imaging, looming actors and images, and form a kind of dreamy virtual scene. Casting light from the front to the gauze can show the image painted on the gauze; when the light is cast from the back of the screen to the gauze, the image drawn in front of the screen appears to cease to exist. To a great extent, it enhances the stage tension of the performance and makes the audience feel the magical world brought about by multimedia dance images.

2. Holographic projection to expand the level of stage space
The light and thin folding of the gauze makes it get rid of the fixed shackles in use, and it can be suspended in front of the stage, in the middle, and so on, and the tilt angle of the gauze can also be determined by the projection angle. The imaging medium composed of gauze can provide a good response of imaging visual effect. Compared with the traditional projection screen, the gauze greatly expands the level of stage space.

3. Holographic laser projection technology enhances the interactivity of the performance
The audience can see the object on the back of the screen through the gauze, and its light transmittance can be used for secondary imaging, which is more transparent than the traditional projection screen. Gauze projection shortens the distance between the audience and the performer, enhances the interaction between the performer and the audience, integrates the multimedia dance images from the performance into the performance, and makes the performance more complete.
