双折射材料的温度修正 Birefringent Material Temperature Modification 7UqDPEXU]` o)Px 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: NC YOY R%\<al$O 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline fo<nk|i |oQhtk8. 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline 9JeT1\VvHY m63>P4h? 3.Loop over the baseline material samples and determine the number of wavelength entries VMS3Q)Ul G7KOJZb+D 4.Loop over each sampled wavelength entry in the baseline material xCyD0^KY #Fgybokm a.Modify the ordinary and extraordinary refractive index values using (2) above 7\H_9o0$ hM&VMa [ b.Apply the modified values to the non-baseline material jF(R;?, '5A&c( 5.Set a description on the non-baseline material indicating the temperature change from baseline s!]QG 7f*b5$+r 脚本编程及GUI例程请下载链接: !Q}Bz*Y 0IHAoV60 http://fred-kb.photonengr.com/files/2011/04/modifyBirefringentMaterialIndex.frs tVNFulcz$ HcV,r,>e http://fred-kb.photonengr.com/files/2011/04/birefringentMaterialTemperatureModification.frd M+)ENve w}M)]kY mi@uX@ # QQ:2987619807 =AF;3
