High-resolution spectroscopy in the field

摘要

This paper gives an overview of the activities on Infrared Fourier Transform Spectroscopy at the TNO-Physics and Electronics Laboratory. Spectra are shown for aircraft plume emission and transmission through wildfire smoke and missile plume smoke. These examples demonstrate the possibilities of these techniques to identify gases and to determine their concentrations and temperatures. Calibration techniques are discussed, which are required to obtain quantitative data on emission and transmission.
