Feasibility of Multi-Parameter Measurement for FBG Perimeter Security Sensor

FBG-based perimeter security is a new security method. It can be distributed security and intelligent addressing. So far, it has been widely used in a variety of security. During the idle time of fiber Bragg grating (FBG) perimeter security defense system, the available FBG perimeter sensor can be utilized as temperature sensor, frequency sensor and acceleration sensor according to its characteristics. The sensor can collect more real-time environment information that make the defense system functions more perfect and more powerful. All of this information can help us to understand the changes in the environment and avoid some accidents.
