Analysis and Optimization of Thermodiffusion of an FBG Sensor in the Gas Nitriding Process

Analysis and Optimization of Thermodiffusion of an FBG Sensor in the Gas Nitriding Process

In this paper, we report the numerical calculations for a thermo-optical model and the temperature sensitivity of a fiber Bragg grating (FBG) sensor. The thermally-induced behaviors of a FBG sensor in the gas nitriding process were analyzed for temperatures ranging from 100–650 °C. The FBG consisted...
