Summary:

This work goals at designing and developing a vibration sensor based on fiber optics and it is a component of the Structural Health Monitoring (SHM) system. The main component of the SHM system is a network of sensors (strain, vibration, acoustic, et cetera) that can track the physical condition of the structures in real time and assist in identifying the beginning of any damage. During flight, launch vehicles typically experience extreme dynamic stresses such shock, random vibration, aerodynamic, and thermal. The assessment of health and the detection of any part detachment or loosening of sub- assemblies are greatly aided by vibration monitoring.Compared to traditional electrical sensors (such piezoelectric or capacitive), SHM systems based on fiber optic sensors show promise because of their EMI resistance, ease of integration into structures, and widespread sensing capabilities. Multiplexing capability of optical fibers is the main additional benefit for system monitoring the numerous dispersed sensors. Surface- bonded and embedded fiber bragg gratings (FBG) are commonly utilized configurations for aircraft and flight structure monitoring. The frequency of vibration changes, or the frequency signature changes, as structural damage is beginning. Thus, a vibration sensor provides vital information about the structure's condition before any catastrophic damage occurs
