双折射材料的温度修正 Birefringent Material Temperature Modification <89js87 FoEZ1O< 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: kmP0gT{Sj >j$f$*x 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline <rCl %GHHnf%2Z 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline 4q~l?*S 55yP.@i9J 3.Loop over the baseline material samples and determine the number of wavelength entries t(ZiQ<A [bv.` 4.Loop over each sampled wavelength entry in the baseline material 57HMWlg @NV$!FB< a.Modify the ordinary and extraordinary refractive index values using (2) above #"f:m` %3kqBH!d b.Apply the modified values to the non-baseline material Nzr zLK 6}|/~n 5.Set a description on the non-baseline material indicating the temperature change from baseline lffw7T~ (j cLzq 脚本编程及GUI例程请下载链接: B8;ZOLAU gNxnoOY http://fred-kb.photonengr.com/files/2011/04/modifyBirefringentMaterialIndex.frs @gTpiV2 R;,&CQUl http://fred-kb.photonengr.com/files/2011/04/birefringentMaterialTemperatureModification.frd OP<@Xz /n:s9eq ~ae68&L6 QQ:2987619807 Gz6FwU8L
