Radiused sensors for measuring pressure and temperature

Abstract

A Fabry-Pérot sensor assembly includes an optical element defining a Fabry-Pérot optical cavity therein. A sensor ferrule is affixed to the optical element. The sensor ferrule is configured to physically connect to an optical fiber, optically aligning and spacing the optical fiber with the optical cavity. The sensor ferrule defines a bore for receiving the optical fiber. The bore extends along a longitudinal axis that extends to the optical element. The optical cavity is a second optical member defined between a first optical member and a third optical member spaced apart from the first optical member along the longitudinal axis. At least one of the first optical member and the third optical member includes a radiused surface bounding the optical cavity and spanning across the optical cavity laterally relative to the longitudinal axis.
