Abstract
An optical projection apparatus including an illumination system, a reflective light valve, an imaging system, and a reflective component is provided. The illumination system is suitable for providing a light beam and the reflective light valve is disposed on a transmission path of the light beam. The reflective light valve is used for converting the light beam into an image. In addition, the imaging system is disposed on the transmission path of the image. The reflective component is disposed both between the reflective light valve and the imaging system and between the reflective light valve and the illumination system, and disposed on the transmission path of the light beam and the image. The reflective component is used for reflecting the light beam onto the reflective light valve, and then reflecting the image produced by the reflective light valve into the imaging system.
