Influence of Waveform Characteristics on LiDAR Ranging Accuracy and Precision

Sensors, 2018
Time of flight (TOF) based light detection and ranging (LiDAR) is a technology for calculating distance between start/stop signals of time of flight. In lab-built LiDAR, two ranging systems for measuring flying time between start/stop signals include ...

Implementation of a Pulse-Holding Time-to-Digital Converter on an FPGA

, 2013
In this work, we describe the implementation of a pulse-holding Time-to-Digital Converter (TDC) on a Xilinx Spartan 6 FPGA. We describe the operation of a pulse-holding TDC and we compare it with that of a pulse-shrinking TDC, which is the most similar ...
