Interferometric stress birefringence measurement

Applied Optics, 1992
We describe a sensitive method for measuring the stress birefringence of an optical window that utilizes a phase-measuring Fizeau interferometer incorporating a variable retarder and a nonpolarizing beam splitter. When we test a material in an interferometer cavity, the wave front transmitted through the material is deviated by the surfaces ...

Birefringence measurements of liquid crystals

Applied Optics, 1984
A convenient and accurate technique for measuring the birefringence of liquid crystals at discrete wavelengths or as a continuous function of wavelength in the ultraviolet, visible, or infrared spectral regions is described. The method is based on determination of the phase differences which occur when monochromatic polarized light propagates through a

Birefringence measurement by speckle statistics

Applied Optics, 1985
The statistical polarization properties of speckle patterns are used to develop a method for measuring birefringence inherent in a speckle producing process. A formula is derived for the mean value of the second Stokes parameter as a function of the birefringence and of the angular orientation of the linear retarder. Measurements have been successfully

Measurements of birefringent media properties using optical vortex birefringence compensator

Applied Optics, 2007
We present some applications of the optical vortex birefringence compensator, based on the C polarization type singularities generated using two Wollaston compensators. The theory and experimental results of birefringent media properties measurements are presented.
