以高分辨率为目标，通过引入三级非对称光瞳函数，得到了具有正反两面的非对称点扩散函数。好的一侧侧叶减少，而不好的一侧侧叶增加。研究发现，这种不对称性随着狭缝孔径内边缘条宽度的增加而增加。另一方面，不存在点扩展函数的不对称性与幅度切趾程度的依赖关系。但发现光学旁瓣的减少幅度随着幅度变迹的增加而大大增加。
Aimed at high resolution, an asymmetric point spread function has been obtained with good and bad sides by introducing three level asymmetric pupil functions. The good side has decreased side lobes while the bad side has increased side lobes. The asymmetry has been found to increase with the width of the edge strips within the slit aperture. On the other hand, there does not appear dependence of the asymmetry of the point spread function on the degree of amplitude apodization. But the magnitude of reduction of optical side-lobes is found to increase to a great extent by the amplitude apodization.
