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: The present disclosure describes optoelectronic modules (e.g., hybrid lens array packages) that have multiple optical channels, each of which includes at least one beam shaping element (e.g., a lens) that is part of a laterally contiguous array. Each optical channel is associated with a respective light sensitive region of an image sensor. Some or all of the channels also can include at least one beam shaping element (e.g., a lens) that is not part of a laterally contiguous array. In some cases, the arrays can include alignment features to facilitate alignment of the arrays with one another.

Abstract: Optical assemblies include a stack of optical elements each of which has one or more alignment features. Each alignment feature traces a respective curve along a surface of one of the optical elements. The alignment feature(s) of one optical element fit within the alignment feature(s) of the other. In some cases, the alignment features can help establish more precise lateral alignment of the optical elements.

Abstract: This disclosure describes optical assemblies that generate output with substantial stability over a wide variation in temperature. The optical assemblies can be integrated, for example, as part of array generators arranged to project an array or other pattern of dots onto an object or projection plane.
