Abstract

Time-correlated single-photon counting techniques have been applied to time-of-flight ranging and imaging. This article describes recent progress in photon-counting systems performing surface mapping using point-by-point acquisition of noncooperative targets at short ranges of the order of 1-50 m, as well as measurements on distributed targets at longer ranges of the order of a 100 m to a few kilometers. We describe the measurement approach, the signal analysis methodology and algorithm selection. © 2007 IEEE.
