Analysis of laser pulses for gaining surface features of urban objects

In this paper we describe investigations for a detailed analysis oflaser pulses. Different techniques for measurement of time resolvedlaser pulses are presented. An experimental system for fast recordingof signals was built up. For principal investigations a test boardwith urban materials was measured by single photon detection techniqueand visualized by a data cube. Based on this spatio-temporal datafeatures are extracted to describe macro, meso, and micro structures.The pictures are depicted by gray value images. The limitation ofan airborne system based on single photon detection is discussed.     «
