The transverse resolution of two zone leaky annular pupil filter increases with the central transmissivity decreasing, and in common cases axial resol.
二区漏光环型光瞳滤波器横向分辨率随中心透过率的减小而增大，一般情况下轴向分辨率随中心透过率的增大而增大。
The results indicate that flat-top beam shaping and single-circle beam shaping at the focal plane can all be realized by using three-zone annular phase pupil filters.
模拟结果表明，利用三环相位光瞳滤波器，不仅可以在焦面上实现光强的平顶分布，而且还可以得到单环衍射光束。
