近几年来,光纤传感元件或传输元件已经成为光纤应用的一个新的有前途的领域。光纤传感器与其它各类传感器相比,不仅具有抗各种干扰和灵敏度高等优点,而且由于它细长柔软,具有几何多面(机动)性,为设计制造各种复杂的光学、光电仪器提供方便。光纤传感器可用于传感各种物理量,如声压、磁场、电源、温度、速度、位移等,经过研究试验,必将得到广泛的应用。由于人体的内脏和
In recent years, optical sensing elements or transmission elements have become a new promising area for optical fiber applications. Compared with other types of sensors, optical fiber sensors not only have the advantages of resistance to various interferences and high sensitivity, but also provide convenience for designing and manufacturing various complicated optical and optoelectronic instruments due to their slimness and softness and geometric polygon (mobility). Fiber optic sensors can be used to sense a variety of physical quantities, such as sound pressure, magnetic field, power, temperature, speed, displacement, etc., after research and experiment, will be widely used. Due to the internal organs of the human body
