A real-time measurement method for both birefringence dispersion and azimuthal angle is described. An optical set-up of this measurement consists of a white light source, two polarizers and two reterders without any rotation. A spectroscopic intensity is detected by a spectrometer. It is modulated with two different frequencies along wave number. Only the single spectroscopic intensity is sufficient to determine the retardation and the azimuthal angle with wavelength-dependence using two amplitude spectrum and phase by the fast Fourier transform method. A birefringence measurement of a Babinet-Soleil compensator as a sample is demonstrated experimentally.
