Abstract

A stereographic projection optical system comprises a light-emitting device, which emits light; polarized light-splitting device, which receives the light emitted from the lighting-emitting device and converts the light to two beams of polarized light for emitting, with polarization directions of the two beams being perpendicular to each other; and a projection device which receives the polarized light emitted from the polarized light-splitting device and realizes imaging of the polarized light. The stereographic project optical system is simple in structure and convenient for installation.

Description

technical field [0001] The invention relates to the field of stereo imaging, in particular to a stereo projection optical system. Background technique [0002] Imaging technology continues to develop, with higher and higher pixels, and we are able to see clearer, brighter, and colorful videos and graphics on larger screens, but they always have a limitation, that is, they are two-dimensional. The real world seen by our eyes is not just a simple flat image, but a stereoscopic three-dimensional with depth of field. This ability to perceive three-dimensionality is a side function of retinal inconsistency (or a slight shift in the position of an object seen by the left and right eyes) . Therefore, if a stereoscopic projection device is to be designed, it must simulate the parallax of retinal imaging when humans watch objects. This sense implies that what we see is real (or almost real), rather than flat and two-dimensional. [0003] Stereo projection is realized through the p...
