  • Patent number: 11631431
    Abstract: Apparatus and method for transferring data in a data storage system, such as but not limited to a hard disc drive (HDD). An optical link is provided between an analog front end (AFE) of a data storage device controller circuit (SOC) and a preamplifier/driver circuit (preamp) mounted to a rotary actuator to transfer an analog domain signal. A selected component is extracted from the signal using a modulation element such as a micro-resonance ring (MRR) or a Mach-Zehnder Interferometer Modulation (MZM) device. The extracted component is forwarded to a processing circuit to facilitate a transfer of data between a local memory and a non-volatile memory (NVM). The optical link includes a flexible portion in a flex circuit affixed to the rotary actuator and which supports the preamp. Multiplexed read, write, and power control signals are concurrently transmitted via the optical link. The link can concurrently service multiple head-disc assemblies (HDAs).

  • Publication number: 20230062555
    Abstract: An optical receiver includes a parasitic current compensation circuit having a reference diode, a sense avalanche photodiode (APD), at least one DC voltage source, and a measurement node. The at least one DC voltage source is configured to generate a first DC bias voltage that varies over time and drives the reference diode, and generates a second DC bias voltage that varies over time and drives the sense APD. A reference parasitic current travels through the reference diode based on the first DC bias voltage. A sense current travels through the sense APD based on the second DC bias voltage and exposure of the sense APD to a light signal. The measurement node receives a sense photocurrent, which is generated by the sense APD in response to the exposure of the sense APD to the light signal, the sense photocurrent including the sense current less the reference parasitic current.

  • Publication number: 20230062298
    Abstract: Interference mitigation for a LiDAR system includes identifying a presence or absence of interference from a non-co-located light source in a sample of incident light received by a detector in the LiDAR system. In the absence of interference, a nominal set of reference values is used for one or more spacio-temporal scanning profile trajectory parameters. Scanner components of the LiDAR system are controlled using the nominal set of reference values. In the presence of interference, the nominal set of reference values is augmented to modify the spacio-temporal scanning profile trajectory parameters. Scanner components of the LiDAR system are controlled using the augmented set of reference values to avoid detection of and interference by the non-co-located light source.

  • Publication number: 20230029105
    Abstract: Method and apparatus for using light detection and ranging (LiDAR) to assist the visually impaired. In some embodiments, a LiDAR system is affixed to a selected finger of a user and used to emit light pulses within a field of view (FoV) before the user. Reflected pulses are detected to generate a point cloud representation of the FoV. A sensory input is provided to the user that describes the point cloud representation of the FoV. The sensory input may be haptic, auditory or some other form. In some cases, a glove is worn by the user and a separate LiDAR system is affixed to each finger portion of the glove to provide a composite scanning and detection operation. Preconfigured hand gestures by the user can be used to change the operational configuration of the system.

  • Publication number: 20230012158
    Abstract: Apparatus and method for enhancing resolution in a light detection and ranging (LiDAR) system. In some embodiments, an emitter is configured to emit a first beam of light pulses over a baseline, first field of view (FoV). Responsive to an activation signal, a controller circuit directs the emitter to concurrently interleave a second beam of light pulses over a second FoV within the first FoV. The first and second beams may be provided at different resolutions and frame rates, and may have pulses with different waveform characteristics to enable decoding using separate detection channels. The interlaced beams provide variable scanning of particular areas of interest within the baseline FoV. The second beam may be activated based on range information obtained from the first beam, or from an external sensor. Separate light sources operative at different wavelengths can be used to generate the first and second beams.

  • Publication number: 20230008801
    Abstract: Method and apparatus for enhancing resolution in a light detection and ranging (LiDAR) system. In some embodiments, an emitter is used to emit light pulses at a first resolution within a baseline, first field of view (FoV). A specially configured optical element, such as a refractive optical lens, is activated responsive to an input signal to direct at least a portion of the emitted light pulses to an area of interest characterized as a second FoV within the first FoV. The second FoV is provided with a higher, second resolution. In some cases, all of the light pulses are directed through the optical element to the second FoV. In other cases, the first FoV continues to be scanned at a reduced resolution. A rotatable polygon, micromirrors and/or solid state array mechanisms can be used to divert the pulses to the optical element.

  • Publication number: 20220413110
    Abstract: Method and apparatus for light detection and ranging (LiDAR). In some embodiments, an emitter is used to emit a set of pulses to impinge a target, and a detector is used to detect a corresponding set of reflected pulses. Range information associated with the target is extracted using the reflected pulses. To compensate for doppler shift and enable more emitted pulses to be in-flight between the system and the target, a maximum expected doppler shift is determined, and the emitted pulses are provided with differential frequency intervals that are greater than the determined maximum expected doppler shift, such as a multiple (e.g., 2×) of the maximum expected doppler shift. In some cases, each in-flight pulse will have a unique frequency separated from all other pulse frequencies by at least the maximum expected doppler shift. Adaptive adjustments can be made such as increasing the differential frequency intervals for long distance targets.
