Abstract:
1. An off-axis image projection system, comprising; an illuminating source, emitting an illuminating beam; a color splitter, for splitting the illuminating beam into a plurality of color illuminating beams; a plurality of reflective displaying devices, respectively receiving and modulating the color illuminating beams to form a plurality of color image-formation beams; a projecting lens set, wherein light paths exist between the projecting lens and the reflective displaying devices; a color combining device, implemented between the reflective displaying devices and the projecting lens set, for combining the color image-formation beams to form an image-formation beam to enter the projecting lens set along the light paths; and a plurality of plate sets, respectively implemented between the projecting lens set and the reflective displaying devices, wherein the plate sets respectively reflect the color illuminating beams to the reflective displaying devices by a non-zero incident angle.
