A system for outputting partially spatially coherent light to an imaging system is disclosed herein, which includes a spatially coherent light source configured to output a spatially coherent signal, at least one optical device having an optical device body with a first device surface formed thereon and configured to reflect a portion of the spatially coherent signal to form at least one coherent reflected signal. The optical device body also includes a second device surface having one or more surface irregularities configured to diffuse a portion of the spatially coherent light source output signal transmitted through the optical device body, to produce at least one spatially incoherent signal. The combination of the coherent reflected signal and the spatially incoherent signal form the partially spatially coherent light signal.
