Abstract: PURPOSE: A patch-type extrinsic fabry-perot interferometer fiber optic sensor and a real time structural vibration monitoring using the same are provided to control the vibration of a structure by developing the extrinsic fabry-perot interferometer fiber optic sensor. CONSTITUTION: A patch-type extrinsic fabry-perot interferometer fiber optic sensor includes a first single mode optical fiber(11), a second single mode optical fiber(12), and a direction detecting sensor(20). The first single mode optical fiber(11) and a second single mode optical fiber(12) are inserted into both ends of a quartz tube(14) and have an air gap formed between the both ends. The first single mode optical fiber(11) and the second single mode optical fiber(12) are flexed to the both ends. The direction detecting sensor(20) is fixed to an outer peripheral surface of the quartz tube(14). The direction detection sensor includes piezoelectric.
