摘要： A compact optical projection apparatus. An apparatus for light projection includes at least one illumination device; a cover prism including a curved surface positioned to receive illumination light rays and a total internal reflection surface positioned to internally reflect the light rays towards an asymmetric reflector surface positioned opposite the total internal reflection surface, the asymmetric reflector surface configured to reflect the received light rays out of the cover prism at an emitter side of the cover prism; a spatial light modulating the illumination light rays with image data to form image light rays; a reverse total internal reflection (RTIR) prism positioned between the spatial light modulator and the emitter side of the cover prism and further comprising a total internal reflection surface configured to totally internally reflect the image light rays out of the RTIR prism into a light projection device. Additional apparatus are disclosed.
