    双折射材料的温度修正 Birefringent Material Temperature Modification @]X5g8h  
    SB =%(]S  
    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: >0.a#-u^

    1.Retrieve the node numbers for the two materials, KDP and KDP Baseline oO][X

    2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline C !6d`|

    3.Loop over the baseline material samples and determine the number of wavelength entries kyu PN<?

    4.Loop over each sampled wavelength entry in the baseline material Z$:iq

    a.Modify the ordinary and extraordinary refractive index values using (2) above A7=k 9|

    b.Apply the modified values to the non-baseline material Vc$y ^|=
