  • Publication number: 20240146290
    Abstract: A light source drive circuit according to an embodiment includes: a first delay circuit (10) that gives, based on a clock signal, a delay to an input signal with first time resolution and a second delay circuit (20) that is connected in series to the first delay circuit, gives, based on the clock signal, a delay to an input signal with a second time resolution having accuracy different from accuracy of the first time resolution, and outputs the signal as a signal for driving a light source.

  • Publication number: 20220291342
    Abstract: Proposed is a ranging system capable of improving the accuracy of ranging. A ranging system (70) includes: a drive unit (24) that causes a light emitting element to emit light and outputs a drive signal for irradiating a target with light; a sensor unit (302) that detects reflected light from the target; a measurement unit (23) that measures a delay time that is included in a time from timing at which a trigger signal for causing the light emitting element to emit light is output to timing at which the light emitting element actually emits light; and a ranging observation unit (52) which is a processing unit that performs a process of calculating a distance to the target on the basis of output timing of the trigger signal, light receiving timing of the reflected light obtained by the sensor unit, and the delay time.

  • Publication number: 20220107420
    Abstract: An object of the present technology is to provide a light receiving device by which an optical displacement having occurred in a light receiving section during manufacturing and assembling, etc. can be corrected. The light receiving device (10) of the present technology includes a light receiving section (2) including a pixel array (16), and a control section (3) that defines multiple pixels included in the pixel array (16) as an active pixel (Pa) and a non-active pixel (Pb) and causes a signal outputted from a pixel defined as the active pixel (Pa) to be outputted from the light receiving section (2).
