  • Publication number: 20230045083
    Abstract: A time of flight (TOF) measurement method and apparatus are provided, including a controller, a time to digital converter, a pulse transmitter, and a pulse receiver. The controller is configured to control, in a working period according to a predetermined transmit rule, the pulse transmitter to sequentially send M transmit pulses. The pulse receiver is configured to receive N feedback pulses in the working period. The time to digital converter is configured to obtain time of flight information corresponding to the N feedback pulses. The controller is further configured to obtain a target time of flight based on the time of flight information corresponding to the N feedback pulses, and obtain a target distance based on the target time of flight.

  • Publication number: 20220365221
    Abstract: A TOF sensor module is disclosed. The TOF sensor module includes a light source, a beam adjustment assembly, and a detection assembly. The light source is configured to emit m first beams at each of M moments, and transmit the m first beams to the beam adjustment assembly. The beam adjustment assembly is configured to: after adjusting the received m first beams into S second beams, project the S second beams to S regions of a detection surface, where M projection points that are in a same region of the detection surface and to which projection is performed at the M moments respectively have different locations. The detection assembly is configured to receive S optical echo signals from the detection surface at each of the M moments, and convert the S optical echo signals into S electrical echo signals for storage at each moment.
