Laser-Induced-Fluorescence Inspection of Jet Fuels

Abstract: 

An optical inspection system for using laser-induced luminescence to detect the quality of materials, such as fuel. The inspection system comprises an excitation means for illuminating a specimen to cause it to produce fluorescent radiation. The spectral representation of the fluorescence produced by the specimen is compared to a reference spectrum to obtain an indication of the physical characteristics of the specimen.
