双折射材料的温度修正
双折射材料的温度修正 Birefringent Material Temperature Modification IS C.~q2 O9gq <d 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: ~iw&^p|=K ^-;S&= 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline \}-4(Xdaq XLpP*VH3 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline wI#8|,]"z Pms@!yce 3.Loop over the baseline material samples and determine the number of wavelength entries ;%|im? wAMg"ImJ 4.Loop over each sampled wavelength entry in the baseline material _8K+iqMZG mDD.D3RS a.Modify the ordinary and extraordinary refractive index values using (2) above Gk;YAI [f6uwp b.Apply the modified values to the non-baseline material PN}+LOD<t 8(3(kZx S 5.Set a description on the non-baseline material indicating the temperature change from baseline ;!yK~OBxt bT,:eA 脚本编程及GUI例程请下载链接: P-m_], ycGY5t@K@
