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: Various stacks of arrays of beam shaping elements are described. Each array of beam shaping elements can be formed, for example, as part of a monolithic piece that includes a body portion as well as the beam shaping elements. In some implementations, the monolithic pieces may be formed, for example, as integrally formed molded pieces. The monolithic pieces can include one or more features to facilitate stacking, aligning and/or centering of the arrays with respect to one another.

Abstract: A time of flight-based system is operable for ambient light measurements. A method of operation includes detecting, in at least one active demodulation detection pixel, a first particular wavelength and generating amplitude data of the first particular wavelength; and detecting, in at least one spurious reflection detection pixel, a second particular wavelength and generating amplitude data of the second particular wavelength. In a computational device that stores spectrum data corresponding respectively to a plurality of different ambient light source types, an ambient lighting condition is determined based on the amplitude data of the first particular wavelength, the amplitude data of the second particular wavelength and the spectrum data of a particular one of the ambient light source types associated with the amplitude data of the first particular wavelength and the amplitude data of the second particular wavelength.

Abstract: A lens module includes a substrate, a first array of passive optical elements on the substrate, and a second array of passive optical elements separate from the first array. The optical elements of the first array and the optical elements of the second array form multiple optical channels, in which at least one optical channel is a catadioptric optical channel including a reflective optical element and a refractive optical element. The reflective optical element is arranged to reflect light toward the refractive optical element, each optical channel has a corresponding field-of-view, and the lens module has an overall field of view defined by the range of angles subtended by the field-of-view of the plurality of optical channels.

Abstract: Various optoelectronic modules are described that include an optoelectronic device (e.g., a light emitting or light detecting element) and a transparent cover. Non-transparent material is provided on the sidewalls of the transparent cover, which, in some implementations, can help reduce light leakage from the sides of the transparent cover or can help prevent stray light from entering the module. Fabrication techniques for making the modules also are described.

Abstract: The present disclosure describes light conversion modules each having a single laser diode or multiple laser diodes. The light conversion modules can be particularly small in size (height and lateral footprint) and can overcome various challenges associated with the high optical power and heat emitted by laser diodes. In some implementations, the light conversion modules include glass phosphors, which, in some instances, can resist degradation caused by the optical power and/or heat generated by the laser diodes. In some instances, the light conversion modules include optical filters which, in some instances, can reduce or eliminate human eye-safety risk.
