Abstract
A printer for printing on a light sensitive media ( ) includes a light source ( ) and optics. Cross array components and array direction components reduce divergence of the beam from the light. The illumination optics flood illuminates a grating modulator with reduced light beams. Modulator sites on the grating modulator array, are individual addressed which imparts a phase change to the reduced light beams. An imaging lens ( ) directs light from the grating modulator array onto the light sensitive media ( ). The imaging lens ( ) includes a first lens element which converts the light into diffracted and undiffracted light; a spatial filter ( ) which discriminates between the diffracted and the undiffracted light; and a second lens element which reconstructs an image of the modulator sites.
