Birefringence measurement of thin polymer films under tensile stress by a Brillouin scattering method
A Brillouin scattering technique has been applied to investigate the ultra-drawing process of polypropylene films. The gradual elastic changes during the drawing process showed the appearance of anisotropy and birefringence of the sample. Devising the optical geometry of Brillouin scattering measure...
