Abstract: Aspects of the present disclosure involve a transparent structure. The structure may include at least one light source, a transparent light-carrying guide layer optically coupled with the at least one light source. The structure may include refractive layers where a light absorbing feature is operably associated with the light-carrying guide layer to absorb any light not internally reflected in the light guide layer, at least adjacent the light source.

Abstract: A lighting system may include one or more light sources and one or more light guides. A lighting system may be integrated into a window, a skylight, an exterior light such as a headlight, a tail light, or a high center-mounted stop light, or other exterior or interior portions of a system such as a vehicle. The light guide may be embedded in an adhesive layer in a vehicle structure. The light guide may be index-matched to the adhesive layer so that unilluminated portions of the light guide are indistinguishable from the vehicle structure. The light guide may be formed from optical fibers. The optical fibers may include a light-scattering optical fiber that scatters light out of the vehicle structure. The light-scattering optical fiber may be fused to a non-scattering optical fiber that guides light from a light source to the light-scattering optical fiber.

Abstract: An optical device includes a substrate and an optical transmitter, which is mounted on the substrate and includes an optical emitter, which is configured to emit a beam of optical radiation, and a transmission lens assembly, which is configured to direct the beam along a transmit axis toward a target. An optical receiver is mounted on the substrate alongside the optical transmitter and includes an optical sensor and an objective lens assembly, which is configured to focus the optical radiation that is reflected from the target along a receive axis onto the optical sensor. An optical baffle is disposed asymmetrically relative to the transmit axis and has an asymmetrical shape configured to block preferentially stray radiation emitted from the optical transmitter toward the receive axis.

Abstract: Apparatus for optical sensing includes an illumination assembly, which directs a first array of beams of optical radiation toward different, respective areas in a target scene while temporally modulating the beams with a carrier wave having a carrier frequency. A detection assembly receives the optical radiation that is reflected from the target scene, and includes a second array of sensing elements, which output respective signals in response to the optical radiation that is incident on the sensing elements during one or more detection intervals, which are synchronized with the carrier frequency, and objective optics, which form an image of the target scene on the second array. Processing circuitry drives the illumination assembly to apply a spatial modulation pattern to the first array of beams and processes the signals output by the sensing elements responsively to the spatial modulation pattern in order to generate a depth map of the target scene.

Abstract: A window or other component may have glass layers and an interposed polymer layer in which a textured light-scattering layer with a diffuse reflectivity is embedded. The textured light-scattering layer may have a textured polymer carrier film coated with a partially reflective layer such as a metal layer. The polymer carrier film may be textured to cause gaps to form within the partially reflective layer. The gaps may be patterned to form ohmic heating current paths or other signal paths through the partially reflective layer. The partially reflective layer may also serve as an electrode in a light modulator such as a liquid crystal light modulator or other light modulator. Images may be projected onto the textured light-scattering layer. The light-scattering layer may also help extract light from a light guiding layer adjacent to the partially reflective layer.

Abstract: An optical apparatus includes a transparent envelope having opposing first and second faces. An electro-optic material is contained within the transparent envelope and includes molecules oriented in respective predefined directions selected so as to form a geometric-phase structure across an area of the transparent envelope. First and second transparent electrodes are disposed respectively across the first and second faces of the transparent envelope. A controller is coupled to apply a voltage between the first and second transparent electrodes that is sufficient to displace the molecules of the electro-optic material from the predefined directions.

Abstract: An optical module includes a diffractive optical element (DOE) with a transparent conductive trace disposed over a surface of the DOE. An emitter is configured to direct a beam of optical radiation through the DOE. Control circuitry is coupled to measure a resistance of the transparent conductive trace and to control operation of the emitter responsively to the resistance.
