Abstract

Results of nighttime, twilight, and daylight testing of an airborne N2 laser fluorosensor are described. Flight tests were conducted at altitudes from 105 to 308 m on fabricated targets containing a coal solvent, quinine bisulfate, motor oil, and a detergent. Strong signals were obtained from all targets during night tests, but detectivity was reduced with increasing solar background. Based on measured signal strengths, minimum detectable concentrations are estimated for a number of substances.
