Abstract: An optoelectronic apparatus includes an enclosure having mutually-opposing first and second faces. An array of emitters contained in the enclosure is configured to emit beams of optical radiation. Projection optics contained in the enclosure have an entrance face and an exit face and are configured to receive the beams of optical radiation through the entrance face and to project the beams through the exit face. A polarization-based spatial multiplexer is contained in the enclosure and positioned to intercept and direct the projected beams such that the optical radiation having a first polarization is transmitted through the first face, while the optical radiation having a second polarization, orthogonal to the first polarization, is emitted through the second face. A controller is coupled to control a polarization of the optical radiation and thereby control a direction in which the optical radiation is emitted from the enclosure.

Abstract: An electronic device may have an optical system that includes one or more light-based components. The light-based components may include light-emitting components such as light-emitting diodes or lasers and may include light-detecting components such as photodiodes or digital image sensors. The optical system may include a light diffuser. The light diffuser may diffuse light that is being detected by a light-detecting component or may diffuse light that is being emitted by a light-emitting component. Light diffusers in optical systems may be formed from patterned light diffuser layers on transparent substrates. Layers of sealant, thin glass layers, antireflection coatings, and other layers may be incorporated into the light diffusers. The light diffuser layers may operate at visible wavelengths and infrared wavelengths. An infrared light diffuser layer may be formed from a patterned silicon layer such as a patterned layer of hydrogenated amorphous silicon.

Abstract: A camera includes a pulse transmitter for transmitting at a transmit time through an aperture and along an optical path to a target a coherent electromagnetic ranging pulse at a first wavelength range outside the visible spectrum. In some embodiments, the camera includes a reflected pulse detector for receiving a reflected electromagnetic pulse reflected by the target back along the optical path and through the aperture at a detect time subsequent to the transmit time. In some embodiments, the camera includes a shutter positioned for shielding the pulse detector from at least transmit time to an intermediate time between the transmit time and the detect time. In some embodiments, the shutter includes a layer of semiconductor material placed in the optical path at a point between the target and the detector.
