Diffraction by Circular Aperture的意思|示意

The diffraction phenomena by a circular aperture or a phase plate is analyzed by the boundary diffraction wave theory, the analytic expression of its axial intensity is obtained.

本文根据边界波衍射理论分析了圆孔及相位片的衍射现象，得出其轴上光强的解析表达式，并对高斯光束经相位片衍射后的轴上光强进行了数值计算和讨论。

The light intensity distribution of diffraction of circular aperture was investigated by numerical analysis.

利用数值分析的方法分析了由边界波理论公式所得的圆形光阑衍射场的光强分布。

A general diffraction formula for circular apertures is derived. This formula is not limited by the aperture radius and the distance from the screen and can be used as a theory of near field optics.

推导了圆孔衍射公式，该公式不受孔径大小和到屏距离的限制，可以作为近场光学的理论。
