光纤温度和应变特性研究实验仪的开发

Development on Experimental Instrument for Studying the Temperature and Strain Characteristics of Fiber

针对目前光纤传感实验存在的问题，搭建了光纤干涉实验平台．利用计算机与摄像头的配合得到干涉条纹移动数目（取代传统用肉眼观察白屏的方法），利用温度传感器与计算机的结合取代传统的温度计，可以在计算机上同时采集到温度和移动条纹数，实时描绘出温度和条纹移动数目的关系图，或者应变和条纹移动数目的关系．所建立的系统稳定可靠，实验效果好，更具现代科技气息．

This thesis analyses the problems that exist in the fields of fiber-sensor experiment ,and created a flat about optics- intervene, using of computer and camera to replace the traditional dsorganize which are with the eyes to calculate the number of the moving stripes,and using the combination of temperature sensor and computer to replace the traditional thermometer. At the same time the computer can collecte the temperature and the num ber of moving stripes, and real - tim e draw the diagram of the temperature and the numb er of stripes, or draw the relationship of the tension and the number of moving stripes. Experimental results show that the system is stably and reliable, as well as having a age - feeling much more.
