Slab deflection measurement technique based on fiber optic gyro

the development and application of fiber optic gyro (FOG) supply the potential possibility for performing accurate slab deflection measurement. In this research, an algorithm method is put forward for calculating slab deflection based on the output of FOG and an in-door model test was conducted. Experiment reveals that FOG is applicable for structure deflection measurement. Its measurement accuracy will satisfy the requirement of engineering if high-accuracy FOG is adopted.
