In continuation of work performed with the application of the scanning multichannel technique in combination with a photodiode array and a single monochromator we show in the present paper a similar technique combining a CCD camera with a double monochromator system with additive dispersion. Special emphasis is given to a discussion of the reproduction of spectral features with small bandwidth. Examples of applications of this technique are given in terms of high-resolution Raman spectroscopy…

TLDR
Application of SMT results in averaged FSRS spectra with improved signal-to-noise ratios that approach the shot- noise limit, and shows that a similar solvent subtraction procedure is ineffective at removing the noise patterns without SMT.
