A method of load monitoring and judging in the smart structure based on the fiber optics is researched in this paper. The principle of detection and monitoring system for this optical smart structure is illustrated and the experiments of loading and damaged position judgment are conducted. The intensity signals which carry the information of the specimen such as load are recorded. After we analyze the elative curves, the conclusions are given. The experimental data and curves meet preferably to the analysis of theory. The system of monitoring and analysis is approved to be real-time, effective and reliable and the research in this paper offers a new way of application of the special optical intelligent structure.
