一种编码式光纤光栅温度传感检测系统的研制

介绍了一种新的大容量编码式光纤光栅传感测量技术，引入了一种由编码式光纤光栅作为传感探头的温度传感检测系统。该系统采用双波长编码技术．对检测点的位置和温度同时进行编码测量，系统具有精确度高、稳定性好、信息量大等特点。特别是双波长编码测量技术的采用．系统由一维编码增进到二维编码，极大地提高了系统的检测容量，克服了传统的一维编码系统由于光源有限带宽导致的信息容量限制。由于在光纤的同一位置集成多个传感探头，降低了成本，该系统具有很好的市场应用前景。

Study on the Measurement System of Temperature Sensing Based on Encoding Optic Fiber Gratings

A new measurement skill based on encoding optic fiber gratings, which has great capability, is introduced. A measurement system of temperature sensing with encoding optic fiber gratings as sensing gauges is presented. This system takes double-wavelength encoding technology; it measures position and temperature simultaneously. Besides that, this system has many advantages, such as high accuracy, long stability, and wide information. Integrating two more sensing gauges in the same location of the fiber can reduce the cost of this system. In conclusion, this system has a great market potential.
