本文从理论分析、计算机计算、实验验证
以及调制传递函数MTF验算等方面进行了论证
确认摄象管主透镜的物是交叉点
而不是小孔。小孔仅是限制光阑。
By means of theoretical analysis
computer calculation
experimental test and evaluation of modulation transfer function
the object of main lens in camera tube is found to be cross-over and not aperture. The aperture only acts as limiting diaphragm.
