Abstract: The method uses a laser light source (1) for illuminating the sample (10), with detection of the Raman dispersed light and division into its spectral lines via a grid spectrograph (6). The intensity of at least one spectral line is measured at least 10 times per second using a photodetector (8), with fluctuation analysis, autocorrelation, or frequency analysis of the measured intensity values.
