Abstract:
An example includes a system, having: an illumination source configured to produce illumination light; and a spatial light modulator (SLM) optically coupled to the illumination source, the SLM comprising an array of picture elements. The SLM is configured to: receive the illumination light; direct, by a first portion of the picture elements, on state light in a first direction; and direct, by a second portion of the picture elements, off state light in a second direction. The example system includes imaging optics optically coupled to the SLM, the imaging optics configured to receive the on state light from the SLM and to project an image as an image portion of a beam; and non-imaging optics optically coupled to the SLM, the non-imaging optics configured to receive the off state light from the SLM and to project the off state light as part of the beam.
