| Abstract: | The development and successful 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 to structure deflection measurement. Its measurement error is approximately 5%. |
