双折射材料的温度修正 Birefringent Material Temperature Modification )4-!]NsV J]zhwM 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: =hd0Ui>x 9Iq<*\V 4 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline |Kjfh};-C EkRx/ 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline K7.ayM 0 %Tu(>vnuj 3.Loop over the baseline material samples and determine the number of wavelength entries .w _BA) 2L[!~h2 4.Loop over each sampled wavelength entry in the baseline material OwPHp&{ Y yB/F6/B~ a.Modify the ordinary and extraordinary refractive index values using (2) above bA2[=6 {dP6fr1z b.Apply the modified values to the non-baseline material ZR%$f- y29G#Y4J 5.Set a description on the non-baseline material indicating the temperature change from baseline ]dl.~;3~~ 5} <OB-9 脚本编程及GUI例程请下载链接: \,n
