Abstract

This paper describes a compact imaging lidar system capable of detecting fluorescence of substances excited by the third harmonic generator of the YAG laser using CCD camera with gated image intensifier. The system mounted on a small airplane or ships will provide the spreading image of oil spills and classification of substances for clean-up operations. From image data of the water Raman scatters, we present a method to measure the extinction coefficients for the oil film thickness measurement. As the reference to interpret the data obtained in the field, the time-resolved fluorescence characteristics of fuel oils and industrial chemical substances were measured with a streak scope in the laboratory within the wavelength of 350 to 575 nm and with decay time up to 500 ns.
