These results demonstrate that the good symmetry of pupil distribution has a better imaging for the incoherent imaging optical system with a complex pupil.
因此，对于复杂光瞳非相干成像光学系统而言，好的光瞳分布对称性具有更好的空间成像特性。

The second kind of pupil filter can increase the axial and transverse resolution at the same time, which is applicable in 3 dimensional imaging in confocal microscopy.
