$C0NvJf F-tanθ畸变最大显示89度,刚查了手册 ^prseO?A 原文如下: bq[j4xH0X Note that this reference is meaningless for optical 4J0{$Xuu0 systems that use field angles at or greater than 90 degrees. If a system with field angles over 89 degrees is 0-p LCf analyzed with this feature, the maximum computed field angle will be limited to 89 degrees
