摘要
本文以日本Capal EX—731电子程序快门为例,用数学分析和计算程序,精确计算了其通光面积曲线S=f(θ),从而为快门的EV曲线理论计算和特性分析提供了可靠数据。本文提供的分析计算方法,对于计算复杂曲线工作边快门叶片的通光面积是十分有效的。
Taking an txample of Japenses Copal EX—731 electronic program shutter, the open area s=f(θ)is calculated precisely with the digital analysis and calculating program, in consequence, the reliable data are provided for the theoretical calculation and character analysis of EV cure of the shutter.
With the method mentioned, the open area of the shutter leaves in complex shape can be calculated.
