Abstract
A method including emitting, by a light emitter, a first light pulse into an environment at a first time, activating a plurality of light detectors including a first light detector and a second light detector, the first light detector and the second light detector having different fields of view, generating, by the plurality of a light detectors, a plurality of analog signals based on return light reflected from the environment, converting, by a circuit configuration coupled to the plurality of light detectors, the plurality of analog signal to digital data, determining, based on the digital data, distance information associated with one or more objects in the environment.
Claims20
A method comprising:
- emitting, by a light emitter, a first light pulse into an environment at a first time;
- activating a plurality of light detectors including a first light detector and a second light detector, the first light detector and the second light detector having different fields of view,
- generating, by the plurality of a light detectors, a plurality of analog signals based on return light reflected from the environment;
- converting, by a circuit configuration coupled to the plurality of light detectors, the plurality of analog signal to digital data;
- determining, based on the digital data, distance information associated with one or more objects in the environment.
A non-transitory computer readable medium including computer-executable instructions stored thereon, which when executed by one or more processors, cause the one or more processors to perform operations of:
- causing to emit, by a light emitter, a first light pulse into an environment at a first time;
- activating a plurality of light detectors including a first light detector and a second light detector, the first light detector and the second light detector having different fields of view,
- generating, by the plurality of a light detectors, a plurality of analog signals based on return light reflected from the environment;
- converting, by a circuit configuration coupled to the plurality of light detectors, the plurality of analog signal to digital data;
- determining, based on the digital data, distance information associated with one or more objects in the environment.
A system comprising:
- a light emitter configured to emit a light pulse;
- a plurality of light detectors including a first light detector and a second light detector configured to generate analog signals in response to receiving return light, wherein the first light detector and the second light detector have different fields of view;
- a circuit configuration coupled to the plurality of light detectors and configured to convert the analog signals into digital data;
- and
- processor configured to determine range information based on the digital data.
