摘要
海水的温度、深度是其重要的物理参量,为了更安全、准确地监测海水的温度和深度,针对目前海洋温度和深度检测大都采用电信号检测,探头在水中安全性欠佳的不足,利用光纤光栅传感探头为全光学器件、水中安全可靠、易于组成传感器网络进行剖面检测的优点,提出一种基于光纤光栅的海水温度、深度检测系统,阐述了其检测原理,进行了系统及传感探头的设计和研制。结果表明,传感器温度和深度检测的线性度很好,达到0.9999,为海水温度深度检测提供了一种新途径。
Abstract
Ocean temperature and depth are important parameters. At present ocean temperature and depth measurement almost depend on electric signal inspection, so the sensor is not safety in the water. In order to overcome this shortage and improve measurement veracity and safety, a new ocean temperature and depth inspection system was presented based on fiber Bragg grating sensor with its advantages of all optic sensors, underwater safety and feasibility of sensor network, etc. Its measurement principle was described; its system and sensor structure was designed and manufactured. The experiments proved that sensor’s linearity was very good and its value was up to 0.9999. It provides a new way to detect ocean temperature and depth.
