Fresnel Diffraction
菲涅耳衍射
Fraunhofer diffraction deals with the limiting cases where the source of light and the screen on which the pattern is observed are effectively at infinite distances from the aperture causing the diffraction. Fresnel diffraction refers to the general case where those restrictions are relaxed. This makes it much more complex mathematically. Some cases can be treated in a reasonable empirical and graphical manner to explain some observed phenomena.
夫琅禾费衍射处理的是光源和观察屏与孔径的距离可以视为无限远的极限情况。菲涅耳衍射则指的是那些限制条件被放宽的一般情况。这使得数学处理更加复杂。某些情况可以采用合理的经验和图形方法来解释一些观察到的现象。
