Measuring and processing the waveform of laser pulses

The analysis of laser data to extract surface features is of greatinterest. Beside the range values, various information about features of the illuminatedsurface can be gained. In this paper, the surface features range, roughness, and reflectanceare determined using different algorithms for extracting pulse properties. The accuracyof the received results is investigated by the comparison of two measurements of the same sceneat different points in time to evaluate the robustness of feature extraction. The reliabilityand quality of the data and the used algorithms are compared and discussed.     «
