Abstract :
The characteristics of fibre-grating-type sensing tuned by applying torsion stress are studied for both the solid column beam and air-core column beam. The wavelength shift is linear with respect to the torsional angle and torque in the range between -45 and +45°. The tuning ranges are no less than 7 nm
