摘　　要：设计了一种适合海洋抛弃式测量的高速响应光纤光栅温度传感器。通过对传感器的温度灵敏度的理论分析,采用有限元方法对不同结构参数传感器的响应时间进行了仿真和对比分析,设计了一种响应时间为17 ms的传感器,其灵敏度理论值可以达到30.7 pm/℃,适用于海洋温度快速测量。Based on fiber Bragg grating （FBG）, a rapid response temperature sensor suitable for marine disposable measurement was designed in this paper. The temperature sensitivity of the sensor was calculated by theory, and the response time of the sensor with different structural parameters was simulated and analyzed using the finite element method. A sensor with response time 17 ms was designed, and its theoretical sensitivity was calculated to be 30.7 pm/℃. This sensor is suitable for rapid measurement of ocean temperature.
