RESEARCH ON PIEZO-ELECTRIC MATERIALS TO BE USED IN PRESSURE MEASUREMENTS

S. Molto, T. Rubin

Abstract

Quantum-based methods have the potential to become primary standards for the SI unit of pressure, the pascal. Some of these standards are based on the determination of the refractive index of a gas under different pressure conditions by Fabry-Perot (FP)-based refractrometry methods. These methods depend on the control of other quantities, mainly the temperature and the mechanical stability. Ideally, the use of an improved cavity with piezo-electric and elasto-optic characteristics will allow for a novel and improved control of the effects of these parameters.
