ABSTRACT	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 damof 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 specimens.Problems relating to the application of interferometric sensors to detection systems in smart structures are also discussed.
