A holographic projection technology projector

Abstract

The invention relates to the field of virtual imaging technology, and discloses a holographic projection technology projector, including a stage, a rectangular groove is opened on the top of the stage, and a screen is fixedly installed in the rectangular groove, and the top of the stage is located on one side and close to two sides. The rail support seat is fixedly installed at the end position, and the track support seat is fixedly installed on the top of the stage on one side and close to both ends. One side of the rail support seat is fixedly sleeved with bolts and is fixedly connected to the stage through the bolt. Since the track support seat has a certain length, the track support seat can be fixedly connected to multiple rectangular frames through bolts, so as to avoid the projection support I and projection support II from being directly fixed to a rectangular frame in the stage so that the frame is affected by all the projection supports The stress brought by I and the projection bracket II may easily cause the problem of falling off, which improves the stability of the device when it is working.

Description

technical field [0001] The invention relates to the technical field of virtual imaging, in particular to a holographic projection technology projector. Background technique [0002] Holographic projection technology is also called virtual imaging technology. It achieves virtual imaging technology through some unique physical properties of light. There are three main virtual imaging technologies widely used today: rear projection, Pepper's phantom and transparent display screen. Pepper's phantom is the most widely used in large-scale stages, it can provide a realistic 3D stereoscopic display effect to the audience, its main principle is to project the content displayed on the screen into a kind of Polarization effect and the semi-permeable film with an angle of 45 degrees to the screen, so that part of the optical fiber can penetrate the semi-permeable film, and the other part can be reflected. When people's eyes receive the reflected light because the environment is darker t...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing holographic projectors proposed in the background technology, the present invention provides a holographic projection technology projector, which is not easy to collapse the bracket and does not require a large enough pulling force for the semi-permeable membrane. The advantage of not collapsing solves the problem that the support of the bracket by a single rectangular frame in the original equipment will easily lead to the collapse of the bracket and the easy damage of the semi-permeable membrane
