Abstract :
A pair of FBG embedded symmetrically in an elastic bending beam, resulting the two peak wavelengths moving apart with the downwards-applied lateral force and moving together in the same direction when surrounding temperature changes, both linearly. Proper calibration makes such arc-shaped FBG sensor capable of simultaneous measurement of both temperature and lateral force. A module with such structure is studied both theoretically and experimentally.
