Abstract
The refractive index of lyotropic lamellar liquid crystal, swollen by brine, is investigated using Michelson interferometry. The index varia tion with the volume fraction of dilution is linear. This result is di scussed to determine an index characterising the dry lamellae and then to deduce the repeating distance of lamellar ordering. Our results ar e in good agreement with X-ray and neutron scattering measurements.
