对称式塑料光纤束反射传感特性研究

Study on the Sensing Characteristic of Reflection for Symmetry Type Plastics Optic Fiber Bundle

给出了对称式塑料光纤束反射传感特性函数的解析表达式，理论计算与实验结果相一致。在不降低灵敏度的情况下，增大了动态范围，有效地解决了动态范围与灵敏度成反比的矛盾。并能够消除光纤损耗、光源不稳定和反射率变化等因素的影响。

This paper gives a analytical-function of reflective sensing characteristic for symmetry type plastic optic fibe bundle. Its theoretical calculated date is same as the experimental result. The dynamic rang is winden but the sensitivity is not lowered. The question that the dynamic range is inversely proportional to the sensitivity is solved effectively. It can also eliminate the effect caused by the loss of optic fiber,the variation of the light soure intensity and the reflectivity and other factors.
