Image projection device comprising dichroic gradient filters

摘要

The image viewing mechanism has a light source which is decomposed into complementary beams. Each beam crosses matrices reflecting as a function of the image. The reflected beams are recomposed and projected onto a screen. The beam decomposition has a dichroic filter (22) which is sloped with respect to the gradient (HOG) with the orthogonal plane (DOE) to the reflecting surface of the matrix.
