[0003] Stereoscopic projection is realized through the polarization principle of light. The existing scheme to realize stereoscopic projection is to use two projectors to project images synchronously, and the polarization directions of the polarizers in front of the two projectors are perpendicular to each other, so that the two beams produced The polarization directions of the polarized light are also perpendicular to each other, and the polarized light direction will not change when the polarized light is projected to the special projection screen and then reflected to the viewer's position. The viewer can only see the corresponding polarized light image through the left and right eyes of the polarized glasses , so as to generate a stereoscopic sensation in the visual nervous system to achieve the purpose of viewing stereoscopic images. The prior art is still unable to achieve the purpose of viewing stereoscopic images through a projector

Embodiment Construction
[0047] The invention provides a kind of polarizing glasses, a polarizing filter, a projector, and a stereoscopic image system, which are applied in the field of projection technology. The projector of the invention uses a polarizing filter to generate alternate image signal light at a predetermined time such as 120 frames per second. The image frames are alternated in sequence, and the vibration direction of the generated alternating image signal light will not change when it is reflected by the projection screen to the polarized glasses, and the viewer can only see the corresponding image through the left and right lenses of the polarized glasses. That is to say, the viewer receives a left-eye frame, then a right-eye frame, then a left-eye frame, and then another right-eye frame through polarized glasses, thereby generating a stereoscopic sensation in the visual nervous system to achieve the effect of viewing stereoscopic images. purpose, so as to achieve the purpose of viewin...

The invention discloses a pair of polarizing glasses, a polarizing filter, a projector and a stereoscopic image system, and is applied to the technical field of projection. The projector generates alternated image signal lights by adopting the polarizing filter according to a preset time such as the frequency of 120 frames per second; various image frames are alternated in sequence, and the vibration direction of the light can not be changed when the generated and alternated image lights are reflected to the polarizing glasses through a projection screen; a viewer only watches corresponding images through the left lens and the right lens of the polarizing glasses, namely, through the polarizing glasses, the viewer receives one left eye frame, then one right eye frame, then one left eye frame and then one right eye frame, thereby generating stereoscopic feel in a vision nervous system and realizing the purpose of viewing a stereoscopic image so as to achieve the purpose of viewing the stereoscopic image through one projector.
Description
technical field [0001] The invention relates to the technical field of projection, in particular to polarized glasses, a polarized filter, a projector and a stereoscopic image system. Background technique [0002] A projector is a device for projecting image signal light onto a projection screen for imaging. Existing projectors include liquid crystal (LCD) projectors, liquid crystal on silicon (LCOS) projectors, and digital light processing (DLP) projectors. [0003] Stereoscopic projection is realized through the principle of light polarization. The existing scheme to realize stereoscopic projection is to use two projectors to project images synchronously, and the polarization directions of the polarizers in front of the two projectors are perpendicular to each other, so that the two beams produced The polarization directions of polarized light are also perpendicular to each other, and the polarized light direction will not change when the polarized light is projected onto ...
