Hj. Patrick, Self-aligning, bipolar bend transducer based on long period grating written in eccentric core fibre, ELECTR LETT, 36(21), 2000, pp. 1763-1764
A long period grating-based bend sensor featuring direct bend sensitivity a
long with linear, bipolar curvature response is demonstrated. The sensor ca
n be aligned for optimum sensitivity using the slight intrinsic curvature o
f the eccentric core fibre.
