Problems solved by technology

[0003] The current projection system is mainly used in head-up display (Head Up Display, referred to as HUD), micro-laser projection (referred to as micro-projection), augmented reality (Augmented Reality, referred to as AR), virtual reality (Virtual Reality, referred to as VR), etc. However, due to the small volume of the projection device and the limited internal accommodation space, the structure of the projection system located inside the projection device is relatively simple, and the projection methods such as the projection direction are relatively simple, which is inconvenient to use. smaller

Abstract

The embodiment of the invention discloses a projection system, which comprises a first digital micro-reflector, a second digital micro-reflector, an optical axis, a first lens group, a light changing unit, a first projection image surface and a second projection image surface, the first digital micro-reflecting mirror is arranged on the first side of the optical axis, the second digital micro-reflecting mirror is arranged on the second side of the optical axis, and the first digital micro-reflecting mirror and the second digital micro-reflecting mirror are respectively used for emitting light beams; the first lens group is arranged in the light emitting direction of the first digital micro-reflecting mirror and the second digital micro-reflecting mirror; the light changing unit is arranged in the light emitting direction of the first lens group. The projection system has the advantages that the projection direction of the light beam can be effectively changed, use is quite convenient, the application range is wide, meanwhile, the internal structure of the projection system is reasonable in design, and the size of the projection system can be conveniently reduced.

Description

technical field [0001] The present application belongs to the field of optical technology, and in particular, the present application relates to a projection system. Background technique [0002] The projection system first irradiates light onto the image display element to generate an image, and then projects it through the lens. Image display elements of projectors include a transmissive type that generates images using transmitted light and a reflective type that generates images using reflected light. No matter which type, the light of the projection lamp is divided into three colors of red, green and blue, and then images of various colors are produced. Because the component itself can only display monochrome, it is necessary to use 3 components to generate 3 color components respectively. Then the three-color images are synthesized into one image through a prism, and finally projected onto the screen through a lens. DMD (Digital Micromirror Device, the first digital...
