Fast Quantification of Air Pollutants by Mid-Infrared Hyperspectral Imaging and Principal Component Analysis
An imaging Fourier-transform spectrometer in the mid-infrared (1850–6667 cm [Formula: see text]) has been used to acquire transmittance spectra at a resolution of 1 cm [Formula: see text] of three atmospheric pollutants with known column densities (Q): methane (258 ppm·m), nitrous oxide (107.5 ppm·m...
