Abstract

The comparative characteristics of highly sensitive photodetectors for modern lidar systems, like self-driving vehicles and autonomous systems for collision avoidance, sensors for aircraft and marine vessels, atmospheric lidar sensing systems, topographic mapping tools are considered. Estimates of the basic parameters of photodetectors such as sensitivity threshold, dynamic range, time and amplitude resolution, as well as the effect of background light on sensitivity were made for the new-type experimental detector HD-SiPM (high-density silicon photomultiplier) and compared with the APD module and commercial SiPM devices, optimized for ToF LiDAR application. Comparison results show that the HDSiPM looks promising for application in various ToF LiDAR systems.
