Abstract

Fiber Bragg Grating sensor is a kind of widely used new sensors. This paper presents a level based on fiber Bragg grating tilt sensor, with the variation of the tilt angle is converted to optical conversion of the change in deformation mechanism to achieve the measured level of relative horizontal angle measurement, sensor-related design theory is given, and to design sensor sensing structure. The sensor adopts fiber grating method to eliminate reference to temperature and metal bellows packaging method to improve the sensitive strain, and through experiments proved the feasibility of this design.
