Claim 10:
11. A device comprising:
a first emitter;
a first detector; and
a controller, wherein the controller is configured to perform operations comprising:
(i) performing a first scan of a field-of-view (FOV), wherein the first scan comprises:
during a first emission time period, emitting, by the first emitter, a first light pulse at a first emission time, wherein the first emission time has a first time offset from a start time of the first emission time period; and
during a first detection time period, detecting, by the first detector, a first light signal at a first detection time;
(ii) performing a second scan of the FOV, wherein the second scan comprises:
during a second emission time period, emitting, by the first emitter, a second light pulse at a second emission time, wherein the second emission time has a second time offset from a start time of the second emission time period, and wherein the second time offset is different than the first time offset; and
during a second detection time period, detecting, by the first detector, a second light signal at a second detection time; and
(iii) determining whether the first light signal is a spurious signal or a reflection from an object based on the first emission time, the first detection time, the second emission time, and the second detection time.
