The flicker of an erythrocyte (FE) is the random overdampened bending oscillations of its membrane, caused by thermal agitation. The first quantitative study showed that the frequency spectrum of FE is related to the membrane bending modulus and intracellular viscosity. The possibility of biomedical 23 requires more detailed investigations of FE. The present work was aimed at the following: 1) the measurements of the FE spectra in the broadest frequency range; 2) the comparison of the spectra, measured in essentially different optical regimes in order to investigate the spectrum distortions caused by the measuring procedure; 3) the development of both a realistic and an easily formulated theoretical model of FE, taking into account the instrumental effects.
