双折射材料的温度修正 Birefringent Material Temperature Modification _l`d+
\# 00Tm]mMQX 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: BI\ )vr$ Y$3 &?LA 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline ^}JGWGib=+ G:$Ta6= 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline Tm!pAD Sz_bjh yT} 3.Loop over the baseline material samples and determine the number of wavelength entries ({XB,Rm [D!-~]5 4.Loop over each sampled wavelength entry in the baseline material T bMW?Su ET t7?,x@ a.Modify the ordinary and extraordinary refractive index values using (2) above ;VhilWaF- |m x)W} b.Apply the modified values to the non-baseline material ZY_aE %gK@R3p 5.Set a description on the non-baseline material indicating the temperature change from baseline <gvuCydsh :@mBSE/ 脚本编程及GUI例程请下载链接: ;WydXQ}Q^ :<t%Sf http://fred-kb.photonengr.com/files/2011/04/modifyBirefringentMaterialIndex.frs 7R4sd *P\$<4l http://fred-kb.photonengr.com/files/2011/04/birefringentMaterialTemperatureModification.frd >3{#S:
