A 3D-projection optical engine using LCOS image panel

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a projection stereo-optic optical engine, and in particular, a plurality of reflective silicon liquid crystal panels (LCOS) and a polarizing beam splitter (PBS: polarizing beam splitter) to light both polarized light. The present invention relates to a three-dimensional projection optical engine for acquiring a three-dimensional image while improving light quantity by using a light source, wherein the light source is formed of a lamp or a white light emitting diode or a red, green, and blue light emitting diode. And a second polarization beam splitter, and a plurality of color filters are disposed around the polarization beam splitter to separate red light, green light, and blue light into monochromatic light to transmit or reflect incident illumination light, thereby increasing color purity. A plurality of silicon liquid crystal panels are arranged around the polarization beam separator or the color filter to capture the left and right images transmitted or reflected. It accommodates both, and changes the polarization direction to reflect, so as not to discard the left and right polarization to use both, it is characterized in that to ensure a double light amount.
