Abstract:
1. A projector comprising: a light source: a spatial light modulator optically coupled to the light source whereby said spatial light modulator receives light from said light source and wherein said spatial light modulator is adapted to produce spatially modulated light; an imaging optical device optically coupled to said spatial light modulator, wherein said imaging optical device comprises an object plane and receives said spatially modulated light from said spatial light modulator, and wherein said imaging optical device is adapted to image said spatially modulated light; a beam steerer arranged to intercept said spatially modulated light, wherein said beam steerer is adapted to steer said spatially modulated light; a controller coupled to said spatial light modulator and said beam steerer, wherein said controller is adapted to drive said spatial light modulator according to a first portion of a video frame while driving said beam steerer to steer said spatially modulated light in a first direction, and to drive said spatial light modulator according to a second portion of said video frame while driving said beam steerer to steer said spatially modulated light in a second direction; and a relay lens disposed between said spatial light modulator and said imaging optical device; wherein, said relay lens has a object plane located at said spatial light modulator and an image plane that is coincident with said object plane of said imaging optical device.
