Popis:	A polarimetric sensor using high birefringent optic fibre is used to measure strain on the surface of a cantilevered beam. Localization of the sensor is accomplished with either a dual 45° splice or a single 45° splice with mirrored endface. Quadrature signal recovery is obtained using a dual wavelength approach. The sensor's performance characteristics are compared with those of an equivalent fibre optic interferometer. Applications of the polarimetric sensor are then discussed.
