Paper Abstract

A fiber optic sensor adapted to the permanent monitoring of oil wells is described, providing a simultaneous determination of pressure and temperature in a down-hole environment. This sensor includes two interferometric transducers in a serial configuration (Fabry-Perot type for the pressure, including a deformable membrane, and birefringent type for the temperature) and uses spectral modulation encoding techniques to recover at large distances both information without cross-talk and with a perfect down-lead insensitivity.
