Abstract:The test theory and the main structural parameter of submerged F-P optical fiber temperature sensor which was based on the theory of white light interference were researched,and the production technology was introduced.The performance test of the optical fiber strain sensor verifies that the optical fiber strain sensor has the merits of good accuracy lasting and durability,and the monitoring test in the construction stage of Liao-river super-bridge which located in Qin-Shen passenger private line verifies that the optical fiber strain sensor can meet the demands of strain monitoring in concrete structure under the complex conditions of construction field.Because the cost of this kind of sensor less than the quintile of the same kind of imported product,the submerged F-P optical fiber temperature sensor has extensive application foreground.
Keywords:white light interference  F-P optical fiber sensor  strain measurement
