A high-precision large-range fiber-optic interferometric piezometer is designed, packaged, and demonstrated for pore water pressure measurement. The piezometer is an optical fiber extrinsic Fabry-Perot interferometer (EFPI), which comprises a fiber ferrule connector/flat contact (FC/FC) connector an...
