Abstract
Tilt sensor is becoming more and more popular in many engineering fields. With the development of the sensor, tilt sensor with high sensitivity and directional is required in these fields. A simple, compact and high sensitivity fiber-optic directional tilt angle sensor is proposed and experimentally demonstrated in this paper. This novel structure is based on an asymmetrical in-line M-Z inclinometer, as a result, the structure is very compact. At the same time, the structure is easy to fabricate. Because of the asymmetrical structure, different changes happened to the sensor and the sensor can recognize the tilt direction. The tilt angle is obtained by monitoring the resonant wavelength shift and the tilt direction can be obtained from the redshift or blueshift. This structure got a very high sensitivity of 0.935nm/° in a range from -3° to 3°.
