A Fourier transform white-light interferometry for the absolute measurement of fiber-optic extrinsic Fabry-Perot interferometric sensors is presented. The continuous test shows the variation is plusmn0.3 mum when measuring a cavity length of 2300 mum. By combining with an average calculation, the variation of the measured results is only plusmn10 nm.
