Optical fibre sensor for high pressure measurement using an in-fibre grating
At 9th Optical Fibre Sensors Conference (OFS-9), Italy.
04 - 06 May 1993.
A fibre optic sensor for monitoring high pressures, using an in-fibre grating, has been constructed. The method involves tracking the wavelength of peak reflection from an in-fibre grating as it is pressurised. Experimental trials, under the influence of hydraulic pressure, have been carried out and a wavelength shift of 0.22 nm at 70 MPa pressure was observed. The sensor should be an attractive choice for ultra-high pressure monitoring
