Patent attributes
A method for expanding a dynamic range of a light detection and ranging (LiDAR) system is provided. The method comprises transmitting, using a light source of the LiDAR system, a sequence of pulse signals consisting of two or more increasingly stronger pulse signals. The method further comprises receiving, using a light detector of the LiDAR system, one or more returned pulse signals corresponding to the transmitted sequence of pulse signals. The one or more returned pulse signals are above the noise level of the light detector. The method further comprises selecting a returned pulse signal within the dynamic range of the light detector, identifying a transmitted pulse signal of the transmitted sequence that corresponds to the selected returned pulse signal, and calculating a distance based on the selected returned signal and the identified transmitted signal.
