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 10):
A method for dynamically varying gain in a lidar system, the method comprising:\n emitting a light pulse by a light source in a lidar system; detecting, by a receiver in the lidar system, light from the light pulse scattered by a remote target to identify a return light pulse, including detecting an optical signal corresponding to the light; converting, by a light pulse-detection circuit in the lidar system, the optical signal to an electrical signal; amplifying, by the light pulse-detection circuit, the 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 comparing, by the light pulse-detection circuit, 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.
