双折射材料的温度修正 Birefringent Material Temperature Modification @g75T` N s3M84w z 目前,FRED尚不支持“global”温度设置,温度敏感性评估一般用脚本编程来完成,该文档演示双折射材料的折射率随温度变化的问题。附件案例文件包括两个双折射材料模,“KDP”和 “KDP Baseline”, KDP Baseline材料存储在已知温度下的折射率,KDP材料用于储存在“current”温度下的折射率值,定义为与baseline material之间的温度差。一个嵌入的脚本名为“modifyBirefringentMaterialIndex” ,包含在FRED文件中,另外也单独附加。其实现过程如下: \u]CD}/ A&P1M6Of 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline VWshFI "k-ov9yK 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline &'7"i~pC }iSakq' 3.Loop over the baseline material samples and determine the number of wavelength entries LO]6Xd" *|HZ&} 4.Loop over each sampled wavelength entry in the baseline material eh(Q^E;* Z)
