Strain gage óptico, funcionamento e aplicações

Abstract

A long time man has used light signals as a means of communication is through light reflected in mirrors or a lighthouse to guide ships. However, these methods were limited and depended on a direct target and could be affected by natural phenomena such as rain, fog and dust. Studies of the use of light evolved significantly and new technologies have been developed such as optical fiber that allows optical signal to be transmitted over long distances without suffering with naturals phenomena and make turns, this technology was initially widely used in telecommunications, presently put his utility is expanding because there are already sensors made with fiber optics. In this study will be an analysis of the strain sensors in Bragg grating, will see its main features, advantages and how it works, they are also cited some of its applications. With the information provided here is possible to take note of how the fiber opticbased sensors work their main advantages and limitations and where they are used, useful information considering that this is an innovative technology that will be much used.
