双折射材料的温度修正 Birefringent Material Temperature Modification au|^V^m Hc]1mM 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: #[y<h3f] #OWs3$9
1.Retrieve the node numbers for the two materials, KDP and KDP Baseline _wNPA1q0J |QLX.. 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline V=&,^qZ ,g_onfY 3.Loop over the baseline material samples and determine the number of wavelength entries 5L}>+js2 -l H>8+ 4.Loop over each sampled wavelength entry in the baseline material e({fY.)SGo ex\W]5 a.Modify the ordinary and extraordinary refractive index values using (2) above p{q!jm~Nq E[.tQ|C b.Apply the modified values to the non-baseline material 6 1W/BU7O KC:4 5.Set a description on the non-baseline material indicating the temperature change from baseline l&*)r;9 !y-2# 脚本编程及GUI例程请下载链接: RX5.bVp
