Abstract: We describe an interferometer based on the Pancharatnam phase in which the extra phase introduced is of purely geometric origin, with no contributions from the dynamic phase. We use a cholesteric liquid crystal film as a circular analyser, and a sheet polarizer as a linear analyser, to project each polarization state on the next one. This experiment can also be viewed as a demonstration of Berry's phase arising from quantum measurements.
