Abstract: A design for an all-optical temperature insensitive fiber Bragg grating (FBG) based tilt sensor is reported.The sensor is capable of measuring the magnitude as well as the direction of inclination from the horizontal with a complete reversible response over the designed dynamic range of ±45°. The most important feature of the reported sensor is its inherent enhanced tuning capability for its sensitivity. An excellent sensitivity of the order of ∼0.0626nm=° that can further be tuned is observed for the sensor. Experimental results show that a tilt angle resolution better than 0:008° with a tilt accuracy of ∼ ± 0:36° was achieved.
