Abstract

Extension of the photon correlation spectroscopy (PCS) technique in low scattering regime was employed to the samples of whole blood studied. A few times scattered tight from a weak helium-neon laser beam incident on the cuvette with the blood sample was detected by a photo-multiplier, and both temporal intensity autocorrelation functions and power spectra were measured with digital autocorrelator and spectrum analyzer. The potentialities of the qualitative and quantitative determining of the structural characteristics of blood elements are demonstrated. To analyze the blood samples we propose to use the PCS technique extended for the transition regime of scattering from single to multiple. The studies made permits the use of the technique for the in vitro clinical blood testing.
