The use of optical fiber in the tele-communication industry is well known. Initially optical fiber sensors are used as real time detection tool in advance aircraft and space vehicles. In the recent years growing interest is emerged in area of fiber optics base sensors for Civil Engineering structures. These sensors offers many advantages over conventional sensors when applied to civil structures as the overall size of most civil structures poses many problems which may possibly be overcome by using fiber optic sensors. The most important feature of fiber optic sensors is that it serves both as sensing element and signal transmission medium. This paper gives an overview in the development of fiber optic sensors for smart structures. In this research, fiber optic sensors are embedded in concrete cubes to measure linear strain and it has been observed that embedded fiber optic sensors responded very well under the applied loads.
