Infrared detection of liquids on terrestrial surfaces by CO(2) laser heating.


The strong mid-infrared bands of contaminant liquids wetting sand and soil can be remotely detected by 0.103-eV laser irradiation with beam intensity well below that which chars the terrain. Emissions from heated nonvolatile interstitial liquid layers and extinction of thermoluminescence by beam-generated vapors of volatile contaminants are spectrally… (More)
