Two-channel inclinometer based on low-coherence fiber-optic Mach-Zehnder interrogation technique
A two-channel inclinometer based on the gravity-referenced rotation fiber optic sensing system is demonstrated. It measures the angle variations between a nominally vertical reference line in the civil structure and the direction of gravity. By using low-coherence fiber optic Mach-Zehnder interferometric technique, the rotations sensitivity in the two perpendicular vertical planes can be achieved in the 0.2' with the dynamics range of /spl plusmn/5/spl deg/.
