null 光纤传感技术是光信息科学技术专业的专业课。主要讲解了光纤传感的基础知识和光纤传感技术的应用，介绍了光纤传感技术的基本概念、光纤传感器系统的构成、传感用的光纤器件、光纤传感技术涉及的不同调制技术，并重点介绍光纤传感器中的新秀——光纤光栅传感器及光纤陀螺仪，启发学生进一步了解各种不同类型的光纤传感器的特点和应用，使学生对光纤传感器有个清晰的认识和掌握，对学生以后开展科研工作打下良好的基础。 The Technologies of Fiber Optic Sensors The Technologies of Fiber Optic Sensors is a specialized course for students major in Photoelectric Information Science and Engineering, and the students major in Electronic Information Science and Technology. The course comprises five chapters. Chapter one is the basic knowledge of optic fibers and the passive devices. Chapter two is the overview and introduction to the technologies of fiber optic sensor systems. Chapter three is the methods to modulate the light wave translating in the fibers. Chapter four is about the Bragg grating fiber optic sensor and its applications. Chapter five is about the temperature and gas sensors. Chapter six is the fiber optic gyroscope. We expect that students could master the technology of various fiber optic sensors, which may be helpful for them to taking up an occupation or doing research work in the future.
