小孔成像的光学传递函数分析

Optical Transfer Function Analysis of Pinhole Imaging System

根据光学传递函数（ＯＴＦ），提出一种分析小孔成像最佳位置的方法，小孔成像的最佳位置可等效为一个具有“可变光焦度”

Based on optical transfer function,a method is presented to analyze the optimum image plane of pinhole.The optimum image plane of pinhole may be regarded as thin len imaging system with a “variable focal power”
