Projection device for displaying images, has lenses, mirror and double prism for directing derived beams on imagers, where beam`s colors are complimentary to each other, for each of successive spatial chromatic separation sequences

摘要

The device has lenses (L2, L4), a mirror (M1) and a double prism for directing a derived beam (F-D1) on an imager (D1), to illuminate it. Lenses (L3, L5), a mirror (M2) and the prism direct derived beam (F-D2) on an imager (D2) to illuminate it. The prism sends the derived beams coming from the respective imagers, on a projection lens (4). Color of the beam (F-D1) and color of the beam (F-D2) are complimentary to each other, for each of successive spatial chromatic separation sequences. The imagers are of micromirror type and modulate the beams for sending the beams in a modulated form.
