双折射材料的温度修正 Birefringent Material Temperature Modification \GjXsR*b5 >#${.+y 目前,FRED尚不支持“global”温度设置,温度敏感性评估一般用脚本编程来完成,该文档演示双折射材料的折射率随温度变化的问题。附件案例文件包括两个双折射材料模,“KDP”和 “KDP Baseline”, KDP Baseline材料存储在已知温度下的折射率,KDP材料用于储存在“current”温度下的折射率值,定义为与baseline material之间的温度差。一个嵌入的脚本名为“modifyBirefringentMaterialIndex” ,包含在FRED文件中,另外也单独附加。其实现过程如下: &5kjjQ*HB &(z8GYBr 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline y1@"H/nYJ [# H8= 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline @F""wKnV B}TInI%H 3.Loop over the baseline material samples and determine the number of wavelength entries ZI#SYEF6 ql%]$`IV6 4.Loop over each sampled wavelength entry in the baseline material
