Abstract

The design, construction and testing of a fibre optic pressure sensor based on a reflecting Fabry-Perot etalon is described. The etalon comprised one fixed mirror and a second mirror designed to flex under the action of the pressure being monitored. A single multimode fibre was used to connect the passive, remote sensor to the transmitter/receiver section, and dual wavelength referencing was used to eliminate the effects of bending-induced attenuation in the fibre.
