Abstract

Range profiling with high resolution and accuracy can be accomplished using single-photon counting time-of-flight techniques. Detection of target surfaces with high resolution is of importance for several remote sensing applications. The use of laser pulses in the picosecond regime, single-photon avalanche photodiodes and acquisition electronics with high timing resolution provides the tools for improving the range accuracy. This paper gives examples of measured surface profiles and compares the results with simplified theoretical models. The results are discussed with respect to some applications.
