Abstract
Fiber optic TR-EFPI (total reflected extrinsic Fabry-Perot interferometric) sensor is developed to measure the strain of structures, such as building, bridge, aircraft, etc. It has been difficult to distinguish the increase and decrease of the strain from the conventional fiber optic EFPI sensor because their signals only have a sinusoidal wave pattern related to the change of strain. In this study, in order to measure the magnitude and the direction of strain, the fiber optic sensor is simply constructed with the total reflected EFPI sensor probe and the digital signal processing.
