    Abstract: The present disclosure describes structured light projection in which a structured light projector includes a light emitter and a compound patterned mask. The mask includes a spacer substrate that is transparent to a wavelength of light emitted by the light emitter. On a first side of the spacer substrate is a first reflective surface having apertures therein to allow light to pass through. Lenses are arranged to focus light, produced by the light emitter, toward the apertures in the first reflective surface. A second reflective surface on a second side of the spacer substrate opposite the first side has apertures therein to allow light passing through the spacer substrate to exit the compound patterned mask.

    Abstract: This disclosure describes illumination assemblies operable to generate a patterned illumination that maintain high contrast over a wide temperature range. An implementation of the illumination assembly can include an array of monochromatic light sources positioned on an illumination plane, first and second optical elements, and an exit aperture. A chief ray of each light source within the array of monochromatic light sources can substantially converge at an exit aperture. In such implementations light generated by the array of monochromatic light sources can be used efficiently.

    Abstract: This disclosure relates to illumination modules operable to increase the area over which an illumination source, such as a vertical-cavity surface-emitting laser or light-emitting diode, illuminates. Such illumination modules include a substrate having electrical contacts, an illumination source electrically connected to the substrate, a collimation assembly operable to collimate the light generated from the illumination source, a translation assembly operable to translate light over an area, and a mask assembly. In various implementations the illumination source may be rather small in area, thereby reducing the cost of the illumination module. Some implementations of the illumination module can be used for the acquisition of three-dimensional data in some cases, while in other cases some implementations of the illumination module can be used for other applications requiring projected light.
