双折射材料的温度修正 Birefringent Material Temperature Modification 4".I*ij \z6UWZ 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: {S+?n[1r\ qZE3T:S 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline F (kq .3UJ*^(? 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline ;=IJHk1& [?:MIl#! 3.Loop over the baseline material samples and determine the number of wavelength entries SJX9oVJeZ _(?`eWo 4.Loop over each sampled wavelength entry in the baseline material q9_AL8_ &+(D< U a.Modify the ordinary and extraordinary refractive index values using (2) above {hOS0).(w7 #?r|6<4X b.Apply the modified values to the non-baseline material 1yz%ud-l &`s{-<t<L 5.Set a description on the non-baseline material indicating the temperature change from baseline LHx ")H?, "(W;rl
