Abstract

Ahigh pressure sensor based on an optical fiber micro sphere cavity Fizeau interferometer (MSC-FI) is presented in this paper.The sensorwas fabricated by use of a fusion splicer. The achieved pressure sensitivity of MSC-FI sensor was in the range of 500 to 7000pi to be 4×10^-4 nm/psi. With a 10 pm resolution for the wavelength shift detection, the resolution of the device at room temperature for pressure measurement is to be 25 psi. This sensor can be used as a high pressure sensor in downhole application.
