Abstract

A simple approach to providing rapid phase-selective diagnostics with step-scan Fourier interferometers is reported. This approach facilitates the optimization of source conditions for producing transient species. Two low-resolution wideband molecular spectra are obtained in a few minutes: The first one contains all the spectral information from the observed source and the other one is made only from the samples, that are sensitive to a specific source modulation. The methodology of this approach is given and demonstrated experimentally.
