Paper Abstract

The double-polarization method is analyzed as optical means for determining the sign of the change in measurand in interferometric force sensing via fiber tension bending. It is shown that the additional phase shift between the orthogonally polarized and otherwise identical interference signals as introduced under tension bending is small as compared to the initial phase shift (quadrature condition). The method is tested by measuring the axial fiber strain via fringe counting under application of transverse force.
