Improvement on Experiment Teaching of Optical Fiber Displacement Sensor

The experimental teaching of sensor and detection technology is an important part of the course teaching.With the development of optical fiber communication technology,optical fiber sensors have been widely used.They have strong anti-interference ability and are insensitive to some harsh environments.In the experimental teaching of fiber displacement sensor,the analysis and processing of experimental results data is cumbersome,computationally intensive,and sometimes improper data processing often affects students' correct understanding of fiber optic sensor.In the experiment teaching,by guiding students to use Excel software for data processing,the functions of data calculation,calculation and drawing can be realized conveniently and efficiently.Compared with traditional manual methods,the quality of experiment report has been improved obviously,and better experimental teaching effect has been achieved.
