摘要：
In this paper, a theoretical analysis of the optimal package diameter of fiber Bragg grating (FBG) pressure sensors is presented. We use the theory of elastic to analyze the relation between the pressure sensitivity and the package diameter of FBG with different materials, structures. Then we can get the optimal package diameter of FBG pressure sensor for a certain package structure and material. Through the following experiments, it can be proved that the theoretical analysis is correct. This analysis could not only significantly enhance the pressure sensitivity, but also provide the optimal package diameter of FBG for the practical applications.
