摘要

影响光强调制式光纤传感器测量精度的因素很多

对于所设计研制的用于叶轮泵高速转轴径向跳动测量的光纤传感器来说

合作对象所引起的测量误差比较突出。针对这一特点

对光在介质表面散射的特性和介质表面轮廓的分布函数进行了研究

并就其对测量结果的影响进行了仿真计算和分析

从而为该类传感器精度的进一步提高提供了依据。

Abstract

There are many factors that can effect on accuracy of reflective intensity-modulated fiber optic sensor（RIM-FOS）.Operational object is a major element among them to fiber optic sensor

which is used in measurement of radial runout of the high-speed draft of steam turbine

studied in the study.For the reason

scattering characteristic of light on surface of medium and distributed function of outline of medium’s surface are researched

and computes and analyzes on their effect on measuring are studied.All of above are benefit to improve accuracy of the sensors.
