Abstract

A prototype single-mode fiber-based ultrahigh pressure remote sensor based upon a Fizeau cavity using a dual-wavelength coherence reading technique with built-in temperature compensation has been constructed capable of remote operation at distances up to 10 km. A separate fiber-based temperature sensor with similar cavity length was incorporated into the pressure probe to allow the pressure measurement to be corrected for the temperature dependence of the pressure sensor. A range to resolution of approximately 1.67 x 10(4):1 and an overall measurement accuracy of approximately +/-0.69% over a pressure range of approximately 1000 bar have been achieved. This system represents a practical approach for industrial applications, such as measuring the pressure of an oil well.
