本文从减小光阑片的外形尺寸出发,建立起一种圆弧边多边形光阑面积的一整套计算公式及其应用条件,在光阑片的设计中又推出一套新的计算方法。
In this paper, a set of formulas for calculating the area of a circular arc polygon diaphragm and its application conditions are established by reducing the outer dimensions of the diaphragm. A new calculation method is also introduced in the design of the diaphragm.
