US 2022/0091234 A1 · SYSTEMS AND METHODS FOR PRE-BLINDING LIDAR DETECTORS

Abstract

Systems, methods, and computer-readable media are disclosed for a systems and methods for pre-blinding light detectors. An example method may include sending, by a processor of a LIDAR system and at a first time, a signal to a light source of the LIDAR system, the signal causing the light source to provide a light input to a photodetector of the LIDAR system, wherein the light input to the photodetector causes the photodetector to initiate a recovery period. The example method may also include emitting, by a laser of the LIDAR system, a first light pulse into an environment at a second time. The example method may also include receiving, by the photodetector, return light associated with the first light pulse from an object in the environment, the return light reaching the photodetector at a third time, the third time being after the photodetector has ended the recovery period.

Dependent claims

A method comprising:

sending, by a processor of a LIDAR system and at a first time, a signal to a light source of the LIDAR system, the signal causing the light source to provide a light input to a photodetector of the LIDAR system, wherein the light input to the photodetector causes the photodetector to initiate a recovery period;
emitting, by a laser of the LIDAR system, a first light pulse into an environment at a second time;
and
receiving, by the photodetector, return light associated with the first light pulse from an object in the environment, the return light reaching the photodetector at a third time, the third time being after the photodetector has ended the recovery period.

1 more element

A LIDAR system comprising:

a processor;
and
a memory storing computer-executable instructions, that when executed by the processor, cause the processor to:
send, by a processor of the LIDAR system and at a first time, a signal to a light source of the LIDAR system, the signal causing the light source to provide a light input to a photodetector of the LIDAR system, wherein the light input to the photodetector causes the photodetector to initiate a recovery period;
emit, by a laser of the LIDAR system, a first light pulse into an environment at a second time;
and
receive, by the photodetector, return light associated with the first light pulse from an object in the environment, the return light reaching the photodetector at a third time, the third time being after the photodetector has ended the recovery period.

4 more elements

A non-transitory computer readable medium including computer-executable instructions stored thereon, which when executed by one or more processors of a wireless access point, cause the one or more processors to perform operations of:

causing to send, by a processor of a LIDAR system and at a first time, a signal to a light source of the LIDAR system, the signal causing the light source to provide a light input to a photodetector of the LIDAR system, wherein the light input to the photodetector causes the photodetector to initiate a recovery period;
and
causing to emit, by a laser of the LIDAR system, a first light pulse into an environment at a second time, wherein return light associated with the first light pulse is received by a photodetector of the LIDAR system from an object in the environment, the return light reaching the photodetector at a third time, the third time being after the photodetector has ended the recovery period.
