Fluorescence lidar imaging of historical monuments.
What is believed to be the first fluorescence imaging of the facades of a historical building, which was accomplished with a scanning fluorescence lidar system, is reported. The mobile system was placed at a distance of ~60 m from the medieval Lund Cathedral (Sweden), and a 355-nm pulsed laser beam was swept over the stone facades row by row while spectrally resolved fluorescence signals of eac...
متن کاملFluorescence lidar multicolor imaging of vegetation.
Multicolor imaging of vegetation fluorescence following laser excitation is reported for distances of 50 m. A mobile laser-radar system equipped with a Nd:YAG laser transmitter and a 40-cm-diameter telescope was utilized. The laser light was Raman shifted to 397 nm with pulse energies of ˜ 30 mJ. An image-intensified CCD camera with a specially designed split-mirror Cassegrainian telescope was ...

Conservation process, but help to understand the purpose and effect of not reading, but perception is a matter of epistemological roots in philosophy and in modern philosophy the process of understanding a monument-art conservation in connection with the audience is importan...
متن کاملAirborne lidar imaging of salmon.
Lidar images of adult salmon are presented. The lidar system is built around a pulsed green laser and a gated intensified CCD camera. The camera gating is timed to collect light scattered from the turbid water below the fish to produce shadows in the images. Image processing increases the estimated contrast-to-noise ratio from 3.4 in the original image to 16.4 by means of a matched filter.
