摘要

　利用平-凸透镜准直器作扩束耦合光学系统

采用低频斩光器实现光调制.推导了浓度计算的理论公式

并对新鲜牛奶进行了实验测定

其测量精度为1%

实验结果与理论分析相符.结果表明

用光纤传感器测量液体的浓度在灵敏度、精度方面都有较大的改善

并可在线连续测量或控制溶液的浓度.

Abstract

This sensor featuring plane-convex lens collimator for expanding beam and coupling

and a low frequency for light pulse modulation is introduced. The theoretical formulas of concentration of solution have been derived. The milk has been measured experimentally

and the precision of measuring is 1%

The experiemental results are agreement with the theoretical analyses. The experimental results show that the sensitivity and precision of the measuring results using the fiber-optical sensor are largely improved. It can be used to perform the measurement or control of concentration of solution on-line in succession.
