  • Publication number: 20220113374
    Abstract: A system includes a local oscillator (LO) signal generation circuit, a receiver (RX) circuit, and a calibration circuit. The LO signal generation circuit generates an LO signal according to a reference clock, and includes an active oscillator that generates the reference clock. The active oscillator includes at least one active component. The RX circuit generates a processed RX signal by processing an RX input signal according to the LO signal. The calibration circuit checks a signal characteristic of the processed RX signal by detecting if a calibration tone exists within a receiver bandwidth, set a frequency calibration control output in response to the calibration tone being not found in the receiver bandwidth, and output the frequency calibration control output to the LO signal generation circuit. The LO signal generation circuit adjusts an LO frequency of the LO signal in response to the frequency calibration control output.

  • Publication number: 20220113378
    Abstract: One example device comprises a plurality of emitters including at least a first emitter and a second emitter. The first emitter emits light that illuminates a first portion of a field-of-view (FOV) of the device. The second emitter emits light that illuminates a second portion of the FOV. The device also comprises a controller that obtains a scan of the FOV. The controller causes each emitter of the plurality of emitters to emit a respective light pulse during an emission time period associated with the scan. The controller causes the first emitter to emit a first-emitter light pulse at a first-emitter time offset from a start time of the emission time period. The controller causes the second emitter to emit a second-emitter light pulse at a second-emitter time offset from the start time of the emission time period.

  • Publication number: 20220113381
    Abstract: A ranging apparatus is provided which is mountable to a vehicle and emits a transmit wave and receives a reflected wave arising from reflection of the transmit signal from an object to calculate a distance to the object. The ranging apparatus includes a light transmissive window, a heater, and a controller. The light transmissive window permits at least one of the transmit wave and the reflected wave to pass through. The heater works to add thermal energy to the light transmissive window. The controller uses an ambient temperature outside the ranging apparatus and a speed of the vehicle derived from a vehicle speed sensor to control energization of the heater. When the vehicle speed sensor is malfunctioning, the controller controls the energization of the heater as a function of the ambient temperature without use of the speed of the vehicle.

    Abstract: A ranging apparatus is provided which is mountable to a vehicle and includes a transmitter, at least one detector, a light transmissive window, a heater, a snow accumulation condition determiner, a snowfall condition determiner, and a heater controller. The heater works to heat the transmissive window. The snow accumulation condition determiner determines a snow accumulation condition of a surface of the light transmissive window. The snowfall condition determiner determines a snowfall condition around the vehicle. The heater controller works to control energization of the heater depending upon the snow accumulation condition and the snowfall condition. The heater controller stops energizing the heater for a period of time when it is determined that there is neither the snow accumulation on the surface of the light transmissive window nor the snowfall around the vehicle.

A lidar system includes a single optical resonator optically coupled to at least a first laser and a second laser. The optical resonator is formed of an electrooptic material. The first laser and the second laser are optically injection locked to the optical resonator. Moreover, a modulator applies a time-varying voltage to the optical resonator to control modulation of an optical property of the electrooptic material, which causes the first laser to generate a first frequency modulated optical signal comprising a first series of optical chirps and/or the second laser to generate a second frequency modulated optical signal comprising a second series of optical chirps. Further, front end optics transmits at least a portion of the first frequency modulated optical signal and/or the second frequency modulated optical signal into an environment from the lidar system.
