摘　　要：光纤激光传感系统作为一种新型的光纤传感技术,结合了光纤传感的高灵敏度、可分布式测量和不易受电磁干扰等优点,以及光纤激光器的窄线宽和高光信噪比等优势,能够很好地应用于油田、矿山、桥梁、电力以及飞机等领域的测量和安全监控。从两个方面介绍了目前光纤激光传感系统的研究进展,一方面是基于单参量测量的光纤激光传感系统,系统所探测的参量包含了温度、应变、折射率、电流、声波和风速等;另一方面是基于双参量测量的光纤激光传感系统,主要是解决温度与横向应力、应变和折射率等交叉敏感的问题。As a new type of optical fiber sensing technology, the optical fiber laser sensing system combines the advantages of fiber sensors of high sensitivity, distributed measurement capability and less susceptible to electromagnetic interference, with the advantages of fiber lasers of narrow linewidth and high optical signal to noise ratio, so it is used in measurement and security monitoring in the field of oil, mining, bridges, electricity, aircraft and so on. The research progress of optical fiber laser sensing system is introduced from two aspects. One is the optical fiber laser sensing system for the single-parameter measurement, including temperature, strain, refractive index, current, acoustic wave, wind speed and so on; the other is the optical fiber laser sensing system for the dual-parameter measurement, which is mainly used to solve the problem of cross sensitivity of temperature and transverse stress, strain and refractive index.
