Abstract :
A `heterodyne-type¿ detection scheme for use with single-mode-fibre polarimetric sensors is described which overcomes the problems of `fringe¿ ambiguity and small-signal fading normally associated with polarimetric sensors. The system is demonstrated using a length of `bow-tie¿ fibre as a simple strain sensor.
