• Note (General): The first section of this report reviews the use of fiber-optic strain sensors in smart structures. Several types of fiber-optic sensor for strain and damage detection in structures are discussed including the high-birefringence polarimetric sensor, interferometric sensor, sensors which utilize scattered or attenuated light, and sensors which combine optical fibers and detectors such as a birefringent sensing cube or vibrating wire. Interferometric sensors are shown to be particularly suitable for strain measurement in structures due to their high sensitivity. The second half of this report is concerned with an investigation of Michelson and Fabry-Perot interferometric sensors and their use in quantitative analysis. It is apparent that interferometric sensors such as these are suitable for static and dynamic strain measurement in structures and also for the frequency analysis of vibrating structures. The feasibility of these techniques was demonstrated through their use in aluminum alloy and CFRP (Carbon Fiber Reinforced Plastic) specimens. Problems relating to the application of interferometric sensors to detection systems in smart structures are also discussed.; 資料番号: AA0001074000; レポート番号: NAL TR-1323
