Embodiment Construction

[0029] First of all, it should be noted that the P-polarized light and S-polarized light described in this article are synonymous with two different linearly polarized lights. P-polarized light and S-polarized light can have multiple meanings, for example, but not limited to the following Any one of a to f is defined:

[0030] a.P polarized light is horizontal linearly polarized light, and S polarized light is vertical linearly polarized light

[0031] b. P polarized light is vertical linearly polarized light, S polarized light is horizontal linearly polarized light

[0032] c. P polarized light is 45 degree linearly polarized light, S polarized light is 135 degree linearly polarized light

[0033] d. P-polarized light is 135-degree linearly polarized light, and S-polarized light is 45-degree linearly polarized light

[0034] e.P polarized light is transmitted linearly polarized light, and S polarized light is reflected linearly polarized light

[0035] f. P polarized light...

Abstract

The invention provides a light recovery device. The light recovery device comprises an optical splitter and secondary optical paths, wherein the optical splitter comprises a plurality of reflection surfaces, and each secondary optical path corresponds to the corresponding reflection surface, the optical splitter is used for transmitting first polarized light and reflecting second polarized light, the reflection surfaces of the optical splitter are used for segmenting an incidence image into a plurality of sub-images, and the secondary optical paths are used for reflecting the corresponding sub-images to a preset area so that the sub-images can be fused into a complete image. The size of the light recovery device can be obviously reduced.

Description

technical field [0001] The invention relates to the field of optical technology, in particular, the invention relates to a light recovery device and a corresponding stereoscopic imaging system. Background technique [0002] In the prior art, in order to obtain the 3D effect, the ordinary polarized light 3D system needs to hit the mixed polarized light (or natural light) emitted by the projector on the polarizer to obtain linearly polarized light, for example figure 1 It shows a schematic diagram of the technical principle of obtaining linearly polarized light in a typical ordinary polarized light 3D system, wherein: P light hits the screen through the polarizer, and S light is reflected back by the polarizer. Like this, in the whole optical path, S light is wasted in vain. Therefore, the brightness of visible light on the actual screen is only half of that before passing through the polarizer. [0003] In order to solve the above problems, people have proposed a light recy...
