Abstract

Provided are methods, systems, and computer program products for a LiDAR with an increased dynamic range. The method includes filtering output pulses of an SiPM device to a substantially symmetric pulse shape and capturing timing information and intensity information of the filtered output pulses for at least one predetermined intensity level. The method includes monitoring saturation of the SiPM device, wherein a width of a saturation plateau of a respective output pulse is determined in response to saturation of the SiPM device. The method also includes extrapolating additional timing information and additional intensity information of the respective output pulse using the captured timing information, the captured intensity information, and the determined width of the saturation plateau.
