双折射材料的温度修正 Birefringent Material Temperature Modification mrIh0B:` S"Lx% 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: *Xo]-cKL0 tZ`Ts}\e 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline c~QS9)=E 0:0NXVYs& 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline 7>iU1zy ;9o;r)9~ 3.Loop over the baseline material samples and determine the number of wavelength entries )^||\G -=s(l.?Hm5 4.Loop over each sampled wavelength entry in the baseline material 5DOBsf8Jo GdV1^`M6 a.Modify the ordinary and extraordinary refractive index values using (2) above m,C1J%{^ \`V;z~@iA b.Apply the modified values to the non-baseline material wo_,Y0vfB 76hOB@ 5.Set a description on the non-baseline material indicating the temperature change from baseline bVP"(H] n
