Time-correlated single-photon counting range profiling and reflectance tomographic imaging

Abstract

AbstractTime-correlated single-photon counting (TCSPC) range profiling and imaging provide high resolution laser radar data applicable in several optical remote sensing applications at short and long distances. Excellent range resolution, below centimetres, can be obtained and information about remote objects can be extracted from TCSPC range profiles. The present study describes a TCSPC range profiling system with subcentimetre range resolution applied for remote sensing of objects at short and longer ranges. Experimental results from interrogation of geometrical shapes, reflectance tomographic imaging and range profiling at longer distance in daylight conditions are presented.
