双折射材料的温度修正 Birefringent Material Temperature Modification f:A1j\A? ^<e(3S: 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: MJ@PAwv" 9C1\?)"D^e 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline S?(/~Vb% H[iR8<rhQ 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline !o`h*G-x yKOC1( ~ 3.Loop over the baseline material samples and determine the number of wavelength entries ;[j)g,7{ k Rp$[^ma 4.Loop over each sampled wavelength entry in the baseline material <3bFt [ :\G`}_db' a.Modify the ordinary and extraordinary refractive index values using (2) above G+Zm K!SFS b.Apply the modified values to the non-baseline material 140_WV?7 8<X;
