Abstract
A Lidar system includes a light emitter and an array of photodetectors. The Lidar system includes a computer having a processor and a memory storing instructions executable by the processor to actuate the light emitter to output a series of shots. The instructions include instructions to provide a first bias voltage to the photodetectors for a first period of time after the light emitter emits a first subset of the series of shots. The instructions includes instructions to provide a second bias voltage to at least one of the photodetectors for a second period of time after the light emitter emits a second subset of the series of shots, the second bias voltage greater that the first bias voltage, the second subset of shots emitted after the first subset of the series of shots.
