Claim 7:
8. An autonomous device comprising a light detection and ranging (LiDAR) device,
wherein the LiDAR device includes:
a light emitter configured to emit modulated light onto an object, the modulated light being modulated to have a first modulation characteristic;
a light receiver configured to receive the modulated light reflected by the object and a plurality of other lights without having the first modulation characteristic, generate a first reception signal based on the modulated light, and generate a plurality of other reception signals based on the plurality of other lights; and
a processor configured to identify the first reception signal as the modulated light that is emitted from the light emitter, based on the first modulation characteristic, and calculate a distance to the object based on the first reception signal without using the plurality of other reception signals.
