Fiber bragg grating (FBG) represents one of the most exciting developments in the fields of passive fiber optical components. Due to its distinct advantages,FBG plays an important role in the area of optical communications and optical fiber sensing. It can detect lots of parameters in some special circumstance. The paper introduces the basic theory of FBG and the FBG based sensor. In oil industry,FBG may be used as sensors of detecting temperature,strain,flow and seismic wave. This is a new design idea of the petroleum instruments,and it will improve the relevant research work in the future.
