摘　　要：文章提出一种用金属管封装光纤布拉格光栅(FBG,Fiber Bragg Grating)温度传感器的方法,以满足海洋快速测温的特殊需求。其响应时间可以达到67.5 ms,而其他光纤温度传感器的响应时间大都是几秒,温度灵敏度可达27.21 pm/℃,线性度可达0.9999,而且长度仅有10 mm。这种传感器的成功研制将为海洋环境温度的监测提供一种新的借鉴。This paper presented a new design scheme of optic fiber sensor which was designed to meet the requirement of fast-response temperature of expendable ocean sensor.The response time of this sensor is 67.5 ms,while that of an ordinary optical fiber temperature sensor is always a few seconds.Temperature sensitivity is 27.21 pm/℃and the linearity is up to 0.9999.In addition,this sensor can be less than 10 mm.It will provide a new reference for the monitoring of marine environmental temperature.
