Abstract
A birefringent-fiber-based dual-channel optical low-coherence reflectometer capable of differential phase measurement is described. Phase noise owing to environmental perturbations that is common to both channels is canceled, resulting in accurate measurement of the phase difference between light ba ckscattered from two spatially separated sites. Results are presented that demonstrate the accuracy and sensitivity of the system. (C) 2000 Optical So ciety of America OCIS codes: 120.3180, 120.5050, 110.4500, 120.1840, 060.24 30.
