Abstract

An imaging system is disclosed that includes an illumination source, a diffractive modulator, imaging optics, and a coherence reduction system. The illumination source is for producing an illumination field. The diffractive modulator is for receiving the at least partially coherent illumination field and producing a modulated illumination field. The imaging optics are for directing the modulated illumination field toward an imaging surface. The coherence of one of the illumination field and the modulated illumination field is reduced.
