Abstract
This memorandum presents a time-resolved Fourier Transform Spectroscopy (FTS) technique developed to measure the spectral emission of gun flashes. The technique is similar to other published techniques for time-resolved FTS of repeatable events. We believe it is original by only requiring the measurement of a small number of events. For example, the cases presented in this document required the measurement of only 25 to 30 flashes. Using such a small set of measurements requires proper corrections of the interferograms. These corrections are explained in the memorandum. With this technique, we obtained results with higher spectral resolution than other published spectra of gun flashes. Since the technique only requires a small number of events, it can be advantageous in cases where it is costly to repeat the events of if unwanted changes in the instrument calibration can occur during the course of the experiment. The technique can also be used without synchronization or triggering devices.
