双折射材料的温度修正 Birefringent Material Temperature Modification pi<TFe@eG .Z:zZ_Ev 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: ="wzq+ U {(U %i\F\ 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline W\&8auds }G4ztiuG 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline }X*Riu7gk 0Z[oKXm1p 3.Loop over the baseline material samples and determine the number of wavelength entries FKNMtp[` ydRC1~f0 4.Loop over each sampled wavelength entry in the baseline material p2Zo n!p<A.O7@ a.Modify the ordinary and extraordinary refractive index values using (2) above VCXJwVb .Asv%p[W b.Apply the modified values to the non-baseline material S}p4iE"n q\m2EURco 5.Set a description on the non-baseline material indicating the temperature change from baseline @=}YTtq \7Jg7 * 脚本编程及GUI例程请下载链接: OQW#a[=WQ x=ul&|^7D http://fred-kb.photonengr.com/files/2011/04/modifyBirefringentMaterialIndex.frs 79`AM
