Abstract

A method for the passive remote monitoring of chemical vapors by differential FTIR radiometry is explored. This approach is based on the use of a double-beam Fourier transform IR spectrometer optimized for optical subtraction. The method 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 presented and tested. The method has been successfully used to map the integrated path-concentration of a vapor plume of ammonia.
