Abstract:
The present invention relates to an illuminator (10, 30, 40) comprising a spatial light modulator (14) including an array of elements (16) each adapted to selectively transmit incoming light without altering the direction of the light, or alter the direction of incoming light; a lamp (12) arranged to illuminate the modulator; a lens (20, 42) for directing unaltered light from the modulator onto an illumination surface (24); and means for forwarding essentially all light altered in direction by the modulator towards the illumination surface.
