Spectrophone Analysis of Gas Samples Obtained at Field Site.
Abstract
An exploratory study of the absorption of atmospheric gaseous samples from a White Sands Missile Range remote site was undertaken. The technique used a state-of-the-art laboratory spectrophone with gaseous samples which were obtained at the remote site in a highly purified stainless steel cylinder. Each sample was cryogenically pumped to obtain atmospheric pressure when the sample was expanded into the spectrophone. The purposes of the study were: To measure the absorption atmospheric gas at 3.5 to 3.8 micrometers and 9.2 to 10.8 micrometers wavelengths using, respectively, deuterium fluoride (DF) and carbon dioxide (CO2) lasers as high resolution spectral sources, and to determine whether the resulting spectral patterns could be analyzed (deconvolved) to determine the identity and concentration of the absorbing atmospheric molecules. These results are directly applicable to Army high energy laser and electro-optical sensor modeling of infrared (IR) transmission in window regions.
