Super-Resolved Raman Spectra of Toluene and Toluene-Chlorobenzene Mixture

In this paper, we present a method for super-resolved Raman spectroscopy which improves the resolution of obtained spectra. Experimental investigations were carried out on the spectra of toluene and a toluene-chlorobenzene mixture. A tunable Fabry-Perot filter is added to the detection channel and by measuring the spectra for several states of the filter a spectrum of higher resolution can be obtained after a decoding process. We demonstrate both a reduced linewidth in the pure toluene spectra and partial separation of the two overlapping peaks in the mixture.
