Paper Abstract

Although there are lots of research papers on the intensity modulated fiber sensors, a very important problem is always neglected, which is the effect on the intensity modulation caused by perpendicularity between the axes of fiber pair and the reflector. Though several papers gave some literal description that the axes of fiber pair should be perpendicular to the reflector, few of them put forward a precise model and quantitative analysis. Just thinking about this, the mathematical model on this effect is established. The simulation curves with different obliquity of the reflector are computed and plotted. Results show that the obliquity of reflector has great influence on modulation function. So advice is presented that the axes of fiber pair should be perpendicular to the reflector.
