    双折射材料的温度修正 Birefringent Material Temperature Modification  #4?Z|_j3  
    9 8O0M#|d  
    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: 4K{<R!2I

    1.Retrieve the node numbers for the two materials, KDP and KDP Baseline 9OI&De5?=V  
    (^,4{;YQ5  
    2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline 9b88):[qO  
    AXBf\ )[  
    3.Loop over the baseline material samples and determine the number of wavelength entries Tp-<!^o4  
    lyZ[t PS  
    4.Loop over each sampled wavelength entry in the baseline material $w%n\t>B  
    uv>T8(w  
    a.Modify the ordinary and extraordinary refractive index values using (2) above fZ8at  
    ^6c=[N$aW  
    b.Apply the modified values to the non-baseline material U5_1-wV

    5.Set a description on the non-baseline material indicating the temperature change from baseline x.J% c[Q8
