Abstract

An imaging system based on laser-induced fluorescence has been developed by using a nitrogen laser at 337 nm as the excitation source. The laser has an output energy of 175 mJ-per-pulse and a beam divergence of 3 mrad. The laser radiation is directed into an all-reflector telescope (basically a hybrid Newtonian type) with variable amounts of off-axis condition. The laser output is reflected to a six-inch concave, spherical secondary mirror by an adjustable off-axis primary mirror. The illuminated area is imaged by using a blue-enhanced, image-intensified CID camera (Xybion XES).
