Abstract:
To decrease the likelihood of a false detection when detecting light from light pulses scattered by remote targets in a lidar system, a receiver in the lidar system includes a photodetector and a pulse-detection circuit having a gain circuit with a varying amount of gain over time. The gain circuit operates in a low-gain mode for a time period T 1  beginning with time t 0  when a light pulse is emitted to prevent the receiver from detecting return light pulses during the threshold time period T 1.  Upon expiration of the threshold time period T 1,  the gain circuit operates in a high-gain mode to begin detecting return light pulses until a subsequent light pulse is emitted.

Claim (Index 1):
A lidar system comprising:\n a light source configured to emit a light pulse; and a receiver configured to detect light from the light pulse scattered by a remote target, the receiver including:\n a photodetector that detects an optical signal corresponding to the light; and \n a light pulse-detection circuit configured to convert the optical signal to an electrical signal and to detect whether the converted electrical signal is indicative of the light pulse scattered by the remote target, the light pulse-detection circuit including:\n a gain circuit configured to amplify the converted electrical signal by a predetermined amplification amount that varies according to an amount of time that has elapsed since the light pulse has been emitted, and \n a comparison circuit configured to compare the amplified electrical signal to a threshold amount to determine whether the amplified electrical signal is indicative of the light pulse scattered by the remote target.
