近20年來的研究與發展已證實了光纖陀螺儀在導航控制系統中的潛能。 其穩定簡單的結構比傳統轉子型的陀螺儀來得方便許多。 世界各國已有許多團隊對光纖陀螺儀感興趣，除了學術單位，工業團體中研發、製造及系統工程師都投入這方面的領域。然而，儘管光纖陀螺儀結構簡單，仍有許多敏感的誤差來源。本文探討光纖陀螺儀之光纖長度與靈敏度及動態範圍之關係，並分析其信號處理方式，將實驗與理論做比較並提出改進之方法。 The research and development for the recent twenty years have identified the potential of the fiber-optic gyroscope, which is now considered a privileged technology for future applications of inertial guidance and control. Its stable and simple configuration brings advantages over the previously conventional approaches by using spinning wheels. Interests in the fiber-optic gyroscope are growing rapidly in many companies around the world. Development, production, and system engineers are now getting involved, in addition to the scientific and technological communities that have conducted the research. However, the fiber-optic gyroscope is still an instrument with many subtle error sources. In this thesis, we study the relationship with sensitivity between fiber length and dynamic range of the system. We also analyze the method of signal processing, to compare the result of experiment with theory, then bring up the method to improve them.
