In Fraunhofer diffraction of a slit, the slit widths obtained with the fringes produced by polarized light whose vibration is parallel or perpendicular to the slit edge are different.

在狭缝的夫琅和费衍射中，由振动平行和垂直于缝边的偏振光的衍射条纹得到的缝宽值不同。

There will therefore be very little diffraction parallel to the edges of the slit.

因此，在平行于狭缝两端边界的方向上，几乎没有什么。
