Embodiment Construction

[0026] see figure 1 , a two-dimensional optical engine, the required light beam is output from the white light source 1, and the IR and UV rays are filtered by the IR-UV cut-off device 2 before entering the color wheel 3. Through the rapid rotation of the color wheel 3, red, green and blue light beams are obtained in turn. Afterwards, it passes through the light rod 4 and the lens group 5, and after being reflected by the mirror 6', it enters the prism group 8 through the lens group 7', and performs a series of transmission, reflection and refraction between the prism group 8 and the DMD 9. The output is finally imaged on the screen 11 through the projection objective lens 10 .

[0027] The present invention is an improvement on the above-mentioned two-dimensional optical engine, and the three-dimensional optical engine of the present invention will be further described below in conjunction with the accompanying drawings.

Abstract

This invention discloses a single chip two-color wheel stereographic projection optics engine, which can realizes the stereographic image output and comprises the following: light source, IR-UV shut, color wheel, optical wand, relay lens set, reflection lens, prism set, digital microscope chip, projection lens orderly arranged along the light path; and splitter, refection lens, polarized pad, lens and prism. The said splitter is located between the IR-UV shut and reflection lens; the said reflection lens, polarized pad, lens set and color wheel are two and symmetrically located around the prism along the light path; the said prism is located between the color wheel and light path.

Description

technical field [0001] The invention relates to a projector, in particular to an optical engine capable of realizing stereoscopic image output. Background technique [0002] Stereoscopic image is a filter technology that utilizes polarized light. When outputting images, set linear polarized light or elliptical polarized light in front of the two rapidly alternately output images to separate the polarization states of the left-eye image and the right-eye image, and then synthesize and project on the screen. The viewer wears polarized glasses, and the polarized glasses can only see respective images, and the images that can only be seen by the left (right) eye are synthesized into a stereoscopic image. [0003] Compared with two-dimensional display, stereoscopic display can provide more comprehensive information of the scene, and its advantages are obvious. [0004] As an important part of video display and computer peripherals, projectors play an irreplaceable role in vario...
