Abstract :
A fiber optic tilt senor for simultaneous measurement of 2-D tilt angle and temperature is proposed and demonstrated experimentally. The sensing head consists of two fiber Bragg gratings (FBGs) attached on a specially designed columnar pendulum. Reflection peaks of the FBGs split and resonant wavelengths shift with tilt and temperature variations. A maximum tilt angle sensitivity of 0.074 nm/°, accuracy of 0.18°, and temperature sensitivity of 0.021 nm/°C have been achieved within the tilt angle range of 0°–40°.
