光纤传感器是众多传感器中的一支新秀,由于它具有许多独特的优点,因而在军事和工业中得到十分广泛的应用,引起了人们越来越大的关注。光纤传感器的工作原理是基于在许多应用中,光纤既是测量媒体又是传输媒体。利用光纤能测量一些影响光沿光纤传输的外部作用参数(温度、压力、场强等)这一特性,已制造出用于各种不同目的的传感器,其工作性能在许多方面都接近甚至超过电子传感 Fiber optic sensors are among the many sensors in the rookie. Due to its unique advantages, fiber optic sensors are widely used in military and industrial applications, attracting more and more attention. The working principle of optical fiber sensors is based on the fact that in many applications, optical fiber is both a measurement medium and a transmission medium. The use of optical fibers to measure the effects of external parameters (temperature, pressure, field strength, etc.) that affect the transmission of light along an optical fiber has resulted in the manufacture of sensors for a variety of purposes whose performance in many ways approaches or exceeds that of electronic Sensing
