碩士 === 國立高雄大學 === 電機工程學系碩士班 === 103 === In this thesis, we demonstrated a fiber ring laser gyroscope which combined with fiber Bragg grating sensor (FBG) and fiber optic gyroscope (FOG) in a system. By using the fiber ring laser structure, it can increase the strength of the source signal and enhance the stability of angular speed measurement. We compare two configuration of the fiber ring laser gyroscope with its signal characteristics and measurement stability. In addition, we also discuss the factors of modulation frequency, minimum angular velocity, and the variation of wavelength displacement of the fiber Bragg grating to the measurements of the fiber ring laser gyroscope. It shows that fiber ring laser gyroscope has effective sensing technique of angular speed measurement and is potential to apply it in environmental sensing and civil engineering structure monitoring.
