摘要
衍射孔径线度与衍射光强存在一定的缩放关系,这一关系可以应用于微小尺寸的工程测量。本文对衍射缩放定理进行了开发,给出了用于单缝和小孔的测量公式以及光电面接收修正因子的表达式。文中还给出了以细丝为例进行的测量实验的结果。
There is a reducing-enlarging relation between the dimension and the diffracting intensity for an aperture.This relation may be used for the engineering measurement of tiny dimension. In this paper the reducing-enlarging theorem is developed. The measuring formulas used for slits and apertures,and the expresions of the correcting factor for the photoelectric receiving with an area are given. In the paper the results of measuring experiment to take filaments for example are also given.
