Paper Abstract

A measurement method of birefringence dispersion by geometric phase is described. The measurement system consists of a polarizer, a quarter wave plate, a rotating analyzer and a spectrometer. The detected intensity by a spectrometer changes sinusoidaly along wave number. A phase shifting method is applied to analyze birefringence dispersion. The total amounts of phase change in all of wavelengths are same, because geometric phase produces by cyclic changes of a state of polarization on the Poincaré sphere. The birefringence dispersion of Babinet-Soleil compensator, polymer films and a liquid crystal phase modulator is measured. Compared measured these results with literature values of birefringence dispersion, measured data agrees well. The measurement results shown the birefringence dispersion measurement by geometric phase is available to practical applications.
