Using a photon counting apparatus as a device to measure light intensity, wave particle dualism of light is demonstrated by measuring photon distribution of double slit diffraction.

用光子计数仪作光强检测装置，通过测量衍射后的光子计数的空间分布来演示光的波粒二象性。

When the slit of light source there is definite width W, the width of diffraction fringe should increase, and the minimum resolving angle Δθ k should be increasing, then the resolving power of actual grating system should be decreasing.

当光源狭缝还有一定宽度W时，衍射条纹将增宽，相应最小分辨角Δθk将增大，实际光栅系统的分辨本领将减小。

This paper proclaims similarity of distribution between light strength of monochromic Fraunhofer's single-slit diffraction and square-wave frequency spectrum.

本文揭示了单色光夫琅和费单缝衍射的光强分布与矩形波频谱分布之间的相似性。

The light is admitted through a slit in the curtain across the line of film motion.

利用帘布上的长条形狭缝沿卷片方向的运动来控制光线的进入.

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。
