Abstract:

A knowledge of the variation in the optical properties of liquids with pressure is required in ultrasound-light interaction studies. One parameter used to describe these variations is the piezo-optic coefficient, defined as the change in refractive index produced by a unit change in the applied pressure. The relative adiabatic piezo-optic coefficients of numerous pure liquids and methanol-water mixtures were determined from measurements made on light diffracted by pulsed ultrasonic waves. Absolute values of this parameter for the liquids tested were calculated from a consideration of experimental values previously determined. Results were compared with the theoretical and empirical formulas presently used to compute this parameter and a new empirical equation was obtained. Author
