Abstract
The direct detection of nitroglycerine, ethylene glycol dinitrate, and dinitrotoluene by optoacoustic spectroscopy techniques at 6 μm, 9 μm, and 11 μm is reported. The effect of interference by normal atmospheric pollutants is investigated, and it is found that of those wavelengths used in this investigation the 9-μm and 11-μm spectral regions, using a CO2 laser as radiation source, are the most promising for use in explosive detection.Keywords
