单色非偏振光透过玻璃堆变为线型偏振光的分析计算与测量

摘要

When monochromatic 589 nm unpolarized light transmitted through a pile of glass plates ,the relationship between the number of the glass plates and the degree of the polarization was quantitatively analyzed and calculated .The numerical calculation showed that with the increase of the number of the glass plates ,the degree of the p polarization increased .When the number of the glass plates reached more than 15 pieces ,the degree of the p polarization was up to 1 .Finally ,a test was carried out by designing an experiment .The theoretical value was basically consistent with the experi‐mental results .%定性分析并定量计算了589 nm单色非偏振光透射出玻璃堆，薄玻璃片数目与透射出的p型线偏振光的偏振度的数值关系．数值计算结果表明：随着薄玻璃片数目的增加，最后从玻璃堆中透射出的p型线偏振光的偏振度变大，当薄玻璃片的数目达到15片以上时p型线偏振光的偏振度几乎达到1．最后通过实验进行了验证，实验测量值与理论计算数值基本符合．
