Abstract

A color beam splitting system for reflection projector, it includes: Light source, for emitting light. Four whole photographs are installed on optical path. The light emitted from light source is through 1st whole photograph split into red-blue-green (RBG) light. The red light is through 2nd whole photograph diffracted to change the direction. The blue light is through 3rd whole photograph diffracted to change the direction. The green light is through 4th whole photograph diffracted to change the direction. The red-blue-green light are projected to 3 sets reflection liquid crystal modulator, and will reflect back along original path after separately modulated. The light emitted from light source is through 1st whole photograph and by diffraction to split into red-blue-green light. The split red light is through 2nd whole photograph projected to 1st reflection liquid crystal modulator. The split blue light is through 3rd whole photograph projected to 2nd reflection liquid crystal modulator. The split green light is through 4th whole photograph projected to 3rd reflection liquid crystal modulator. And the light will reflect back along the original path after modulating, and converge on 1st whole photograph to form a light beam and project on screen to form image.
