Abstract

The high-accuracy universal polarimeter (HAUP) uses a technique (HAUP method) for simultaneous measurement of optical anisotropy (birefringence, optical activity, rotation of optical indicatrix, dichroism, electro-optic coefficients,...) of crystals. The HAUP method has been applied to determining linear birefringence and optical activity of Quartz as a function of temperature in the range 25-300 °C at 632.8 nm of wavelenght. The measurements are affected by modulation in the fitted parameters of HAUP method and optical properties when the sample temperature is changed. This effect can be explained by the multiple reflections within the slab that give rise to a temperature-dependent interference pattern. The same effect has been observed in Lithium Niobate and Calcite samples of great plane-parallelism. Good agreement was found between our experimental values and the HAUP method equations in the presence of multiple reflections.
