| Abstract: | This article described the characteristics,application and modulation principle of the reflective optic fiber sensors.Based on a typical reflective fiber optic sensor,the mathematical model of its output characteristics was set up.Besides,the model was simulated by MATLAB,and the function curve between the output optical power and the measuring distance were plotted with different prerequisites.It shows the influence of optic fiber parameters such as the radius of the fibers,the gap between the fiber pairs,... |
