Étude expérimentale de propriétés piézo-optiques du CCl4 liquide

Abstract

We have developed a measuring system based on the Michelson interferometer for the determination of piezo-optical effects in liquids. The resolution of our system is about 5 parts in 107. We applied our system to the measurement of the variation of the refractive index of CCl4 at 25 °C up to 1.96 × 103 bar. We observe a slight deviation of the Lorentz–Lorenz equation at high pressures.
