Abstract:

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.

Key words: ocean temperature sensor, simulation, FBG, rapid response
