Analysis of diffential absorption lidar technique for measurements of anhydrous hydrogen chloride from solid rocket motors using a deuterium fluoride laser

摘要: An active optical technique (differential absorption lidar (DIAL)) for detecting, ranging, and quantifying the concentration of anhydrous HCl contained in ground cloud emitted by solid rocket motors (SRM) is evaluated. Results are presented an experiment which coefficients were measured several deuterium fluoride (DF) laser transitions demonstrating first time that a close overlap exists between 2-1 P(3) vibrational transition DF 1-0 P(6) line HCl, with coefficient 5.64 (atm-cm) to -1 power. These measurements show can be appropriate radiation source detecting DIAL technique. Development mathematical computer model predict sensitivity outlined, results assume commercially available as presented.
