云母双折射率色散关系不一致性对波片设计的影响rn——波片光相位延迟色散的补偿方法

摘要

In designing wave_plate, the problem of inherent discrepancy of birefingent dispersion relations of mica is difficult to resolve. In this paper, the authors present a precisive measuring method for birefingence different from traditional resolution, by which they can determine phase retardation of any sample at any wavelength directly from single wavelength measuring instead of multi_wavelenth measuring. This fast and simpler measuring method can be used in mass production of waveplates.%云母晶体材料本身性质所决定的双折射率色散关系不一致性，对于波片设计是一个棘手的问题. 与传统的样品普遍鉴别测量方法不同的是，该文试图从介绍分析双折射率的精确测量方法入手，通过必要的技术处理，达到直接采用单波长的测量结果代替多波长的测量结果，最终推断出任意波长或任意样品材料对应的波片相位延迟. 此方法较之传统测量方式简捷快速实用，可满足云母波片系列化生产需要.
