双折射材料的温度修正
双折射材料的温度修正 Birefringent Material Temperature Modification }r04*P( NiG&Lw*8 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: -/8V2dv3 K*~xy bA 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline S*r }oX0 kU:Q&[/jzH 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline 4gZ R!J b?k,_;\ 3.Loop over the baseline material samples and determine the number of wavelength entries j\#)'>" .==c~>N 4.Loop over each sampled wavelength entry in the baseline material E=.J*7 HmXxM:[4; a.Modify the ordinary and extraordinary refractive index values using (2) above J;fbE8x 1xxTI{'g[ b.Apply the modified values to the non-baseline material k8Dk;N N#J8 4i;ry 5.Set a description on the non-baseline material indicating the temperature change from baseline NrcV%-+u% *"|f!t 脚本编程及GUI例程请下载链接: ,*$Y[UT a;i}<n7
