Problems solved by technology

[0008] The disadvantage of traditional polarized 3D technology is that there is a loss of brightness
According to the principle of polarized light, this technology can only make the brightness of the picture reach 16% of the original brightness, so the polarized 3D technology has higher requirements on the brightness output of the projector.

Embodiment Construction

[0033] Attached below in conjunction with the manual Figures 3 to 8 , the specific embodiments of the present invention are introduced.

[0034]The polarized 3D system based on the recycling of polarized light according to the present invention is composed of a beam splitter 1 , an optical path adjuster group 2 , a lower polarizer 3 , a screen 4 , a reflector 5 , and an upper polarizer 6 . The light transmitted from the projector is projected on the screen 4 through the beam splitter 1 through the optical path adjuster group 2 and the lower polarizer 3; the other group of light refracted by the beam splitter 1 to the reflector 5 is projected through the upper polarizer 6 to the screen.

[0035] The adjustment of the lower optical path by the optical path adjuster group 2 is as follows Figure 8 shown. The optical path adjuster group 2 can be one optical path adjuster or a plurality of optical path adjusters, and is a device for adjusting the image size in the optical path,...

Abstract

The invention relates to a polarization three-dimensional (3D) system based on polarized light recycling. The polarization 3D system based on the polarized light recycling is composed of a light splitting sheet, a light path adjuster set, a lower polaroid sheet, a screen, a reflector and an upper polaroid sheet. One path of light which is transmitted from a projector penetrates through the light splitting sheet, the light path adjuster set and the lower polaroid sheet and is projected on the screen, and the other path of the light which is transmitted from the projector is refracted on the reflector through the light splitting sheet, light which is refracted on the reflector is then projected on the screen through the upper polaroid sheet. The polarization 3D system based on the polarized light recycling has the advantages that compared with an ordinary polarization 3D system, the polarization 3D system based on the polarized light recycling can achieve double luminance when a 3D film is shown, and the 3D effects of the polarization 3D system based on the polarized light recycling is more obvious and clearer than the 3D effects of the ordinary polarization 3D system; compared with an existing dual-computer 3D system and an IMAX 3D system, the polarization 3D system based on the polarized light recycling is simple in system composition and free of installation requirements of the dual-computer 3D system, and better saves cost.

Description

technical field [0001] The present invention relates to optical systems, and more particularly, to polarized 3D systems based on polarized light recycling. Background technique [0002] Polarized 3D uses the principle that light has a "vibration direction" to decompose the original image. By adding a polarizer on the display screen, two pictures with different polarization directions can be sent to the viewer. When the picture passes through polarized eyes , Since each lens of the polarized glasses can only accept pictures in one polarization direction, the left and right eyes of a person can receive two sets of pictures, and then the brain can synthesize stereoscopic images. [0003] figure 1 Schematic representations of unpolarized and fully polarized light are shown. figure 1 On the left, natural light is uniformly distributed or transmitted in all directions, that is, unpolarized light. figure 1 The right side shows that the light vibrates in the same direction, which...
