Publication number: 20220091269Abstract: 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.Type: ApplicationFiled: September 2, 2021Publication date: March 24, 2022Inventors: Bernhard Buettgen, Gregory A.

Patent number: 11236885Abstract: 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.Type: GrantFiled: May 18, 2020Date of Patent: February 1, 2022Assignee: APPLE INC.Inventors: Boris Morgenstein, Ali M.

Publication number: 20210199871Abstract: 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.Type: ApplicationFiled: March 11, 2021Publication date: July 1, 2021Inventors: Gregory A.
