F-tanθ畸变最大显示89度,刚查了手册 ;ASlsUE\) 原文如下: O8M;q!)y Note that this reference is meaningless for optical =i `o+H systems that use field angles at or greater than 90 degrees. If a system with field angles over 89 degrees is uv Z!3 UH. analyzed with this feature, the maximum computed field angle will be limited to 89 degrees
