Time-resolved discrete interferogram

A rather new approach to time-resolved spectroscopy that uses modem optoelec-tronic-controlled step-scan methods of Fourier transform interferometry has been suggested [53]. When using step-scan interferometry, the initiation of a reversible event must occur at each mirror position. The time evolution at each mirror position subsequent to initiation is then measured at discrete time intervals. Data processing involves sorting by time in order to produce an interferogram for each sampling time. These interferograms are subsequently Fourier transformed to yield a set of time-resolved spectra. To quote the authors ...
