SPAD-based Light Detection and Ranging for 3D imaging: Receiver operation and in-pixel TDC design for automotive application

In this work, a SPAD-based LiDAR system is studied. In particular, the system employs a direct time-of-flight (dToF) method to reconstruct a target-reflected pulses using histogram, from which the distance to the target is estimated. More particularly, a time correlated single photon counting (TCSPC) method has been used to record the flight...
