In-plane vibration displacement measurement using fiber-optical speckle interferometry

Abstract An optical fiber sensor system based on dual beam speckle interferometry is presented. The system provides a noncontact method of very small vibration displacement real-time measurement. It takes advantage of simple optical components and fibers through a signal processing technique capable of measuring vibration displacement components. The theoretical analysis and experimental systems are described. Experimental results show that the in-plane vibration spectrum can be easily established.
