C307 蛍光ライダーによる海洋汚染検知システムについて

This paper describes a newly developed the system to detect spilled chemical substances. We had developed the prototype of fluorescence Lidar since 2001. The Lidar system was able to detect fluorescence of substances excited by the third harmonic generator of the YAG laser using CCD camera with gated image intensifier. The laser beam included 355 (third harmonic), 532 (second harmonic) and 1, 064nm (normal wavelength) light. An ICCD camera recorded images of the oil fluorescence that was excited by 355nm light. Both the sea depth and the observing altitude were measured by the reflectance signal of 532 and 1, 064nm beam. Detection system was composed of there detectors.
We developed a new detection system to measure fluorescence of chemical substance with a high accurately, and confirmed the performance from 2002 to 2003. The system was composed of 4 lenses and an ICCD camera. Through lens mounted a different band-pass filter, four kinds of wavelength images were obtained at the same time as one image. The performance was confirmed by the field experiment and shipboard experiment.
