    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.

    Abstract: An apparatus for producing structured light comprises a first optical arrangement which comprises a microlens array comprising a multitude of transmissive or reflective microlenses which are regularly arranged at a lens pitch P and an illumination unit for illuminating the microlens array. The illumination unit comprises an array of light sources for emitting light of a wavelength L each and having an aperture each, wherein the apertures are located in a common emission plane which is located at a distance D from the microlens array. For the lens pitch P, the distance D and the wavelength L, the following equation applies P2=2LD/N, wherein N is an integer with N≧1. High-contrast high-intensity light patterns can be produced.

    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: 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.
