Paper Abstract

The phenomenon of thermal emission form non-volatile liquid surface coatings following pulsed laser heating has been experimentally and theoretically studied with a view to developing a differential thermal imaging scheme for the remote detection of contaminated surfaces. Pulsed UV and IR laser sources have been used to generate radiance profiles from contaminants which are correlated with their characteristic spectra. Data from experiments and numerical simulations are compared and a reasonable level of agreement is demonstrated.
