Embodiment Construction

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0036] Such as figure 1 As shown, the present invention provides a stereoscopic projection imaging device, including beam size adjustment components, namely lens combinations 102 and 103. The incident beam 137 is incident on the lens combination. By adjusting the lens combination, the incident range can be reduced. Especially in the solution to the solution of the low projection ratio theater, this structure can be applied to a lower proj...

Abstract

The present invention discloses a stereographic projection imaging device and system with high photosynthetic efficiency capable of performing light path recovery to reduce optical energy loss and improve projection imaging quality and suitable for a low-projection ratio cinema environment. The stereographic projection imaging device comprises a polarization spectrometer, a reflection element, a light beam size regulation module, a linear polarizer, a polarization modulator and a polarization converter. The polarization spectrometer is the polarization splitting prism combination or a polarization beam splitter, the reflection element employs a high-reflection polarization element, the high-reflection polarization element is formed by a protective layer, a reflection layer, an absorption layer and a glass substrate, and the polarization converter has a wavelength bandwidth regulation function. The stereographic projection imaging device can effectively reduce the optical path difference of the reflection light beam and the transmitted light beam to allow the whole structure to be optimized so as to greatly shorten the size of the whole device.

Description

Technical field [0001] The invention relates to the technical field of stereo projection, in particular to a stereo projection imaging device and system. Background technique [0002] The stereo projector converts and plays two different sequences of images in frame order. At present, the 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. The three-dimensional images are presented alternately. . The viewer usually wears stereo glasses, through which each eye of the viewer can only see the sub-sequence of the image prepared for it. There are stereo imaging systems for passive stereo glasses. The images of different sequences originally from the projector are non-polarized light beams, and the non-polarized light beams are converted into polarized light beams through the polarization beam splitter configured in the stereo imaging system. [0003] However, most of the existing stereo projec...
