Strain Measurements Using Fibre Bragg Grating Sensor

摘要: Fibre Bragg grating (FBG) sensors are widely accepted as strain and vibration monitoring devices for advanced composite mechanical structures. The advantages of using the FBG include their small physical size, insensitivity to electromagnetic interference, lightweight, multiplex ability be used at relatively high temperature environmentally unfavorable conditions. However, most research related use embedded has only focused on static measurement identification mode shapes fiber optic have been in this work operating feasibility a sensor system real-time an fibre demonstrated experimentally. In paper sensing measurements is being described. Low cost simple grating-based FBGS produce induce wavelength shift. Experimental theoretical results showing capability proposed perform giving linear response presented.
