ABSTRACT:
An optical fibre sensor element (1) comprising an optical fibre (2), a protective coating on the optical fibre, and shape constraining means (3) which causes the optical fibre (2) to follow a path which extends in a generally longitudinal direction and which is such that the coated optical fibre (3) is not perfectly straight and it is impossible to draw an imaginary straight line in any direction which remains inside the coated optical fibre (3) along the entire length of the optical fibre sensor element (1).
