Abstract

High information time-resolved spectra from a stepping-mode Connes-type Fourier interferometer have been recorded in order to test the main limitations of the method1.2. They show a two-fold improvement on both the time resolution (100 ps) and the total number (107) of recorded samples. Doppler-limited spectra of the N2 electronic transition B3Σ−A3Π, emitted from a microwave excited plasma, over a range of 7000cm−1 are presented with a time resolution of 3 μs as an illustration of these new possibilities in wideband time-resolved spectroscopy.
