Design of Reflective Intensity Modulated Fiber-Optic Sensor Based on TracePro and Taguchi Method

Compare with traditional way of numerical simulation by establishing the mathematical model through geometry optic, we design a TracePro model to analyze the sensing process of reflective intensitymodulated fiber optic sensor base on ray tracing. This type of sensor has advantages over other fiber optic sensor, including simple structure, flexible design, reliable perform, low cost etc. In this paper, to design the reflective intensity modulated fiber optic sensor with concave reflected surface, TracePro software is used for modeling, TP modeling results are consistent with the existing conclusions show that the method is reasonably effectively, can improve the design efficiency. Meanwhile the Taguchi method is used to optimize coupling efficiency of receiving fiber in fiber optic displacement sensor design. Through optimizing three controllable factors the optimization configuration of A1B1C1 combinations is gain, presents a viable solution for the design of this sensor type.
