摘要
设计了基于光纤白光干涉测量技术的折射率测量仪, 用来测量尺寸较小、形状简单的透光材料折射率。与传统折射率检测方法相比较, 光纤折射率测量仪具有设备尺寸小、测量精度高、操作简易、便于携带等优点。实验测得某种石英玻璃的折射率值为1.464, 与标准值偏差为0.02, 误差为1.4%; 测得某种普通玻璃的折射率为1.502, 与标准值偏差为0.002, 误差为0.1%; 测得K9玻璃的折射率为1.507, 与标准值偏差为0.009, 误差为0.6%。
Abstract
A refractive index measuring guage based on the white-light interferometry is developed for the measurement of refractive index of small size,smooth and transparent materials. Compared with traditional refractive index detection methods, the guage has many advantages, such as smaller size, higher accuracy, simple operation and portable. Experiment results show that the index of quartz is 1.464 and the deviationis 1.4%,the index of SiO2 is 1.502 and the deviation is 0.1%, the index of K9 glass is 1.507 and the deviation is 0.6%.
