Abstract

The invention discloses a high-light-efficiency stereoscopic projection imaging device and system capable of recycling light paths, reducing light energy loss and improving projection imaging quality, and suitable for a low projection ratio cinema environment. The stereoscopic projection imaging device comprises a polarizing beam splitter, a reflective element , beam size adjustment component, linear polarizer, polarization modulator, polarization state converter, the polarization beam splitter is a polarization beam splitting prism combination or a polarization beam splitter plate, the reflective element adopts a highly reflective polarizing element, and the highly reflective polarizing element It is composed of a protective layer, a reflection layer, an absorption layer and a glass substrate, and the polarization state converter has the function of adjusting the wavelength bandwidth. The stereo projection imaging device provided by the present invention can effectively reduce the optical path difference between the reflected light beam and the transmitted light beam, so that the overall structure is more optimized, so that the volume of the entire device is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of stereoscopic projection, in particular to a stereoscopic projection imaging device and system. Background technique [0002] The stereo projector converts and plays two different sequences of images in frame order. The current mainstream is the left eye image and the right eye image. One sequence is seen by the left eye, and the other sequence is seen by the right eye, and the stereo images are alternately presented. . The viewer usually wears stereoscopic glasses, through which each eye of the viewer can only see a sub-sequence of images intended for it. Stereoscopic imaging systems for passive stereoscopic glasses are currently available. The different sequences of images initially output from the projector are unpolarized light beams, and the unpolarized light beams are converted into polarized light beams by the polarization beam splitter configured in the stereo imaging system.
