Abstract: Light-emitting optoelectronic modules operable to generate an emission characterized by reduced speckle can include a coherent light source, a diffuser, and a Fresnel element. The coherent light source is operable to generate a coherent emission, characterized by a coherence length, incident on the diffuser. The diffuser is characterized by a divergence angle. The divergence angle is the angle between a first path-length from the diffuser to a Fresnel element and a second path-length from the diffuser to the Fresnel element, wherein their difference defines a path difference. In some instances, the path difference is substantially larger than the coherence length.

Abstract: A microlens array diffuser operable to generate a substantially diffuse illumination includes an array of microlenses, wherein each microlens has a respective periodicity-influencing characteristic and a respective surface profile. The array of microlenses includes at least two microlenses having respective periodicity-influencing characteristics that differ from one another and having respective surface profiles that differ from one another. Each surface profile is configured to generate a substantially equal field of illumination. The microlens array diffuser can be integrated as part of an illuminator operable to generate substantially diffuse illumination.

Abstract: For an optical dot projector having multiple light emitters, a relationship is determined between locations of the light emitters with respect to a substrate of the optical dot projector and corresponding first locations of dots projected by the dot projector onto an imaging plane. An optical grating approximating one or more optical characteristics of one or more optical elements of the optical dot projector is determined based on the relationship. Second locations of dots corresponding to a replacement of the one or more optical elements of the optical dot projector by the optical grating are determined, and modified locations of the light emitters with respect to the substrate are determined based on the second locations of dots. Optical dot projectors are constructed according to the determined modified locations.

Abstract: An example system includes an optical element defining a first surface, and a substrate layer defining a second surface and a third surface opposite the second surface. The second surface of the substrate layer is adjacent the first surface the optical element. The system also includes a conductive trace disposed on the third surface of the substrate layer. The optical element is operable to emit light in a first direction through the substrate layer and the conductive trace. The conductive trace defines at least one of an aperiodic path or an irregular path.

Abstract: The current disclosure describes a system for dimming sunlight that interferes with an observer's vision. A position of an observer's eyes and a position of the sun relative to a transparent screen are determined, and, based on the position of the observer's eyes and the position of the sun, an area of the transparent screen where light emitted by the sun intersects the transparent screen before reaching the position of the observer's eyes is identified. The system causes the area of the transparent screen to be modified such that the light emitted by the sun is dimmed in the area of the transparent screen.
