We measured the fluctuations of a lyotropic liquid crystal lamellar (Lα) phase in dilute surfactant concentration and a sponge (L3) phase by dynamic light scattering technique. We observed the concentration fluctuation induced by the thermal undulation of layers in the Lα phase and obtained the dependence of the effective rigidity kc of layers on the repeat distance d, which reflected the fluctuation-induced layer softening. In the L3 phase, two kinds of fluctuation modes were observed.
