Abstract: A proximity sensor includes a light source configured to emit a beam of optical radiation and a detector configured to output an electrical signal in response to the optical radiation that is incident on the detector. A first optical multimode fiber is configured to receive the emitted beam and to direct the emitted beam toward an object. A second optical multimode fiber is configured to receive the optical radiation reflected from the object and to convey the received optical radiation to the detector. A processor is coupled to process the electrical signal so as to compute a distance to the object.

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: An electronic device includes a substrate, a set of light emitters on the substrate and arranged in a plurality of axisymmetric light emitter groups, a set of lenses including a different lens disposed over each axisymmetric light emitter group of the plurality of axisymmetric light emitter groups, and a set of optical fibers. At least one optical fiber in the set of optical fibers has a proximal end, a distal end, and a bend between the proximal end and the distal end. The proximal end is positioned to receive light, through a respective lens in the set of lenses, from the light emitters of a respective axisymmetric light emitter group in the plurality of axisymmetric light emitter groups.

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.
