    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: In some embodiments, the method includes measuring a first responsive voltage value for a first voltage drop between a first terminal attached to a first suspension spring of an actuator housing a voice coil motor for moving a lens assembly and a second terminal of the magnetic coil of the voice coil motor. In some embodiments, the method includes calculating a first resistance of the magnetic coil based at least in part upon the first voltage value and measuring a second responsive voltage value for a second voltage drop between the first terminal attached and the second terminal. In some embodiments, the method includes calculating a second resistance of the magnetic coil based at least in part upon the second responsive voltage value and calculating a relative temperature for the magnetic coil based at least in part upon the first resistance and the second resistance.

    Abstract: In some embodiments, an apparatus for performing temperature-compensated measurement of a position of a lens assembly is attached to an autofocus actuator. In some embodiments, the apparatus includes a light source for emitting light in a first direction. In some embodiments, a measurement sensor is affixed for receiving light reflected from a reflector. In some embodiments, a lateral shield is affixed in a position blocking detection by the measurement sensor of light having been emitted from light source but having not been reflected from the reflector. In some embodiments, a monitoring sensor is affixed in a position relative to the light source to receive light having been emitted from light source but having not been reflected from the reflector. In some embodiments, a transverse shield is affixed in a position blocking detection by the monitoring sensor of light reflected from the reflector.

    Abstract: Some embodiments include a method for measuring the position of a camera lens carrier moveable by an autofocus actuator. In some embodiments, the method includes generating a measurement of a magnetic field resulting at least in part from the one or more position sensor magnets. In some embodiments, the generating the measurement of the magnetic field includes measuring a magnetic field component created at least in part by the one or more position sensor magnets fixedly mounted to the camera lens carrier. In some embodiments, the camera lens carrier is moveably coupled to a substrate by the autofocus actuator to provide motion in a direction orthogonal to the substrate. In some embodiments, the generating the measurement of the magnetic field component includes measuring the magnetic field component at a sensor fixedly mounted to the substrate of the autofocus actuator.
