The birefringence of LC was obtained with only one experimental run by using phase modulation technique, which is an expansion of PMFB (Phase Modulated Flow Birefringence) technique developed elsewhere [1], The basic principle of the method is based on the determination of the phase differences which occur when a phase modulated monochromatic polarized light propagates through a medium with an anisotropic refractive index. Birefringence measurements with red light (wavelength: 0.6328µm) for commercial liquid crystal material (Merck, ZLI 3201-000) are reported.
