  • Patent number: 11781723
    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.

  • Patent number: 11057595
    Abstract: Described examples include an optical device having a first light source configured to provide a first light having a first characteristic. The optical device also has a second light source configured to provide a second light having a second characteristic. The optical device also has a combiner configured to combine the first light and the second light to provide a combined light. The optical device also has a spatial light modulator configured to modulate the combined light to provide modulated combined light. The optical device also has a divider configured to receive the modulated combined light and to direct a first portion of the modulated combined light having the first characteristic to a first target and to direct a second portion of the modulated combined light having the second characteristic to a second target.
