Conclusions We present a vertical line sensor composed of a 1 × 16 array of analog silicon photomultipliers (SiPM) optimized for 3D time of flight (ToF) imaging LiDAR in advanced driver assistance systems (ADAS) and autonomous driving (AD) vehicles. The sensor has been designed for enhanced redsensitivity performance with a PDE of greater than 8% and can operate in outdoor environments with high ambient light noise of 100 klux and targets that have a low reflectivity from 10%. The SiPM array enables long distance ranging greater than 100 m and allows for superior low reflective target distance ranging over APD and PIN diode based systems. The SiPM array is to be demonstrated in an electro-mechanical scanning imaging LiDAR system consisting of a transmitter based on an eye-safe 905 nm laser diode array the 1×16 SiPM array as receiver, collimating optics and an electro-mechanical rotating mirror for horizontal scanning of a 80 × 5 at 30 fps. Simulation results are presented here to validate the concept of long distance LiDAR based on SiPM receivers. The Silicon Photomultiplier for Solid State, Long Distance LiDAR
