| 摘 要： | 用激光作为测量光源,利用激光经玻璃微珠一次或多次内部反射后出射,形成最小偏转角的原理,对高折射率玻璃微珠折射率的测量进行了理论分析和实验测试.比较了不同内反射次数对测量精度的影响.该测量方法尤其适用于已在微珠列阵逆向反光膜上大量使用的、折射率位于1.8～2.4之间的高折射率玻璃微珠折射率的测量,较传统方法具有简便、快捷和安全的特点.经分析和对不同类型微珠样品的实测比较,获得了测量精度优于1%的结果.

| Abstract: | A new method for measuring the refractive index of glass beads is presented.Using a laser beam incidence fulfills the condition of minimum deviation and through one or more times inner reflection,can be received the primary or higher order rainbows which relate to the refractive index of the glass beads.The method is particularly adapted to measure the refractive index within 1.7～2.4 of glass beads,and the features of this method are convenient,quick and safe.Through analyzed and compared with different experiment results,the measuring accuracy is better than 1%. |
