Abstract
A method including emitting, by a light emitter, a first light pulse at a first time; activating a first light detector and a second light detector with different fields of view, emitting, by the light emitter, a second light pulse at a second time; receiving return light by the first light detector or the second light detector at a third time; and determining, based on the return light being detected by the first light detector or the second light detector, whether the return light is based on the first light pulse or the second light pulse when the first light pulse and second light pulse are simultaneously traversing an environment for a period of time.
Claims20
A method comprising:
- emitting, by a light emitter, a first light pulse at a first time;
- activating a first light detector and a second light detector with different fields of view;
- emitting, by the light emitter, a second light pulse at a second time;
- receiving return light by the first light detector or the second light detector at a third time;
- and
- determining, based on the return light being detected by the first light detector or the second light detector, whether the return light is based on the first light pulse or the second light pulse when the first light pulse and second light pulse are simultaneously traversing an environment for a period of time.
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 emit, by a light emitter, a first light pulse at a first time;
- causing to activate a first light detector and a second light detector with different fields of view;
- causing to emit, by the light emitter, a second light pulse at a second time;
- determining return light is by the first light detector or the second light detector at a third time;
- and
- determining, based on the return light being detected by the first light detector or the second light detector, whether the return light is based on the first light pulse or the second light pulse when the first light pulse and second light pulse are simultaneously traversing an environment for a period of time.
A system comprising:
- a light emitter configured to emit a first light pulse;
- a first light detector configured to point in a first direction and having a first field of view, the first field of view associated with a first range from the light emitter;
- a second light detector configured to point in a second direction and having a second field of view, the first field of view associated with a second range from the light emitter;
- a processor;
- and
- a memory storing computer-executable instructions, that when executed by the processor, cause the processor to:
- causing to emit, by a light emitter, a first light pulse at a first time;
- causing to activate a first light detector and a second light detector with different fields of view;
- causing to emit, by the light emitter, a second light pulse at a second time;
- determining return light is by the first light detector or the second light detector at a third time;
- and
- determining, based on the return light being detected by the first light detector or the second light detector, whether the return light is based on the first light pulse or the second light pulse when the first light pulse and second light pulse are simultaneously traversing an environment for a period of time.
