For these two effective focal lengths, the spots on the image surface at zero view field, 0.7-view field and full view field are all inside the airy disc. The system MTF curve of each effective focal length are accordance with the corresponding diffraction limits curve. The biggest wave aberration is smaller than 1/4 wave lengths. The maximum field curvature and maximum f-theta system distortion respectively satisfies the precision demand of the laser marking machine in China.

系统像面在0视场、0.7视场和全视场的光斑都落在相应的爱里斑以内，系统的MTF曲线接近相应的衍射极限曲线，最大波像差小于四分之一波长，系统的最大场曲和最大f-theta相对畸变都很好地满足了国内激光打标机的精度要求。

So even though the geometric focus is smaller than the diffraction disc, the star image 揵lows?

因此我们可以说，这样的结果就是受了衍射的影响，也就是衍射极限。

This is an excellent figure, not that far from diffraction limited.

这是一个极不错的数字，还没有到衍射的极限。

It becomes obvious that the performance is no longer limited by the diffraction of the system.

很明显，整体的表现已经不受衍射极限的限制。

Based on the point spread function of holographic system, the lateral resolution of digital holographic imaging system without any pre-magnification is studied.
