An optical scheme for a remote measurement of mode-coupling coefficients in birefringent fiber is proposed that uses wavelength scanning, white-light interferometry, and two phase-shifted channels for output spectrum detection. The procedure is outlined for two-channel signal processing. This technique can be used to develop distributed fiber-optic sensor for remote sensing. Its experimental verification is presented.
