双折射材料的温度修正 Birefringent Material Temperature Modification _NJq%-,'
PP)-g0^@ 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: 1{X ;&y +q3E>K9a 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline BIjQ8 t vb Mv8Nk 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline T]Eg9Y:+v h wfKgsm 3.Loop over the baseline material samples and determine the number of wavelength entries >)PcK 8L*P!j9`EY 4.Loop over each sampled wavelength entry in the baseline material dg]: JU </8F a.Modify the ordinary and extraordinary refractive index values using (2) above PG/xX
