A novel health monitoring system based on optical intelligent structure is presented and designed.The hardware of this system consists of light resource group

photoelectric sensors

a monitoring host and a personal computer.The software part of the system consists of the monitoring host software and the monitoring PC software.The software of the monitoring host is responsible for the acquiring and processing of the photoelectric signals and communication with PC.Thus the structural state can be analyzed and the monitoring records would be created.The monitoring experiments are carried out at different locations of a E51 composites specimen which is commonly used in aircraft with special fiber optics network buried（space is 3cm）to form the optical fiber intelligent structure.Therefore

the experimental data are analyzed and the damage areas are located.The experimental results show that performance of the monitoring system is reliable

its effect is abvions

it has real-time for the state monitoring of intelligent structure.A new way is offered for state monitoring application of special optical fiber intelligent structure.
