Paper Abstract

The quantization capabilities of a new passive FTIR method for the remote monitoring of chemical vapors are explored. The method is based on the use of a double beam interferometer-spectrometer optimized for optical subtraction.. The instrument is described with a particular emphasis on its capabilities for differential detection and background suppression. The algorithm developed for on-line detection and quantization of chemical vapor plume is also reviewed. The method has been successftilly used to map the integrated concentration and the temperature ofa plume ofmethanol vapor.
