Abstract

The noise of Raman and elastic scattering has been studied by means of intensity value distribution, Fourier spectrum, autocorrelation function and correlation coefficient between both signals. Measurennts have been carried out for inhomogeneous liquid samples which are typical in biological applications of Raman spectroscopy . It. is shown how the statistical properties of noise ei serve for a check on an experimental set-up and a sample quality and for improvement in measuring process. A special procedure is proposed when the Raman and the elastic scatterings are measured simultaneously and the latter signal is used for decreasing of the noise in the Ranian spectriun.
