| 摘 要： | 通过测量激光细光束经平行平板玻璃所产生的位移,可确定平行平板的的折射率。本文阐述了该方法的测量原理,给出了测量公式,并详细分析了测量误差。计算机模拟计算结果表明,当平板厚度为50mm时,如果入射角测量标准偏差为1”,平板厚度和光线位移量测量标准偏差均为0.001mm,则折射率测量的标准偏差可达6×10~(-5),此时入射角约55°。

| Abstract: | By measuring the displacement of laser beam through plane-parallel transparent material, the refractive index of the material can be determined precisely. The principle of this method has been introduced, the formulae of the measurement have been giver and measurement errors analyzed in this paper. Simulative calculation by computer shows when the thickness of plate is 50mm, the standard deviation of incident angle of light is 1" and the standard deviation of plate thickness and displacement of light bcem are 0.001mm respectively , the mininum standard deviation of refractive index measurement if about 6 x 10-5 at (he incident angle 55 . |
