Abstract
Light emitting systems and optical systems including a light emitting system and a lens system are described. The light emitting system includes a pixelated light source having a plurality of discrete spaced apart pixels, and includes a plurality of light redirecting elements, each light redirecting element corresponding to a different pixel in the plurality of pixels. The light redirecting elements may be adapted to alter one or both of a central ray direction and a divergence angle of light received from the corresponding pixel. A lens system disposed to receive light from the light emitting system may include a reflective polarizer and a partial reflector.
