Automated Detection of Trichloroethylene by Fourier Transform Infrared Remote Sensing Measurements

摘要

Passive Fourier transform infrared(FT-IR) remote sensing measurements are used to implement the automated detection of trichloroethylene(TCE) vapor in the presence of a variety of infrared background signatures. Through the use of a combination of bandpass digital filtering and piecewise linear discriminant analysis, this detection procedure is applied directly to short segments of the interferogram data collected by the FT-IR spectrometer.
