The main objective of this project is to establish a fiber-based multi-point dynamic and transient displacement and strain measurements and use these sensors in the vibration control and precision control systems. Laser Doppler vibrometer and strain gage will be used in this project to verify the results obtained from grating-based fiber displacement and strain sensor, respectively. This project will be focused on improving the dynamic displacement and strain measurement ability of the fiber sensor demodulation system. Vibration suppression experiments and precision control will be performed to test the transient detection ability of the fiber sensor system.光纖光柵結構抑振動態位移量測動態應變量測Grating-based fiberVibration suppressiondynamic displacement measurementdynamic strain measurement
