摘要：

In the only measurement to date of the ratio R//d of depolarized to polarized light scattering intensities in the isotropic phase of a cholesteric liquid crystal, Harada and Crooker reported that the value of 3/4 predicted by the order parameter fluctuation theory of de Gennes was not observed. Measurements were made of R//d in cholesteryl oleyl carbonate (COC) using a more precise rotating polarizer technique. R//d is observed to have a strong temperature dependence which can be explained by the de Gennes theory plus an additional fluctuating component as described by Courtens.
