摘要：

We have investigated the multiplexing technique of Fourier transform white-light interferometry recently reported by [Jiang IEEE Photon. Technol. Lett. 20, 75 (2008)]. Two extrinsic Fabry-Perot interferometric sensors are spatially frequency-division multiplexed, and no cross talk is found in the experiment. Besides, an improvement was made to achieve a resolution of 1 nm, which is much better than the previous result, 300 nm.
