The influence of partially coherent illumination on the performance of a few non-Airy pupil functions (Sonine, phase-step, annular, Straubel, and Lansraux-Boivin pupil functions) is studied in the context of microscopic imagery. The imaging properties of these pupil functions are investigated in terms of the two-point image contrast and resolution. It is seen that by adjusting the state of coherence of illumination of the object structure and a suitable choice of the pupil function, a resolution higher than that due to the Airy pupil function may be obtained. It is also possible, in a similar way, to increase the image contrast without unduly reducing the image resolution.
在微观成像的背景下，研究了部分相干照明对几种非艾里光瞳函数（索宁、相移、环形、施特劳贝尔和朗斯洛 - 博温光瞳函数）性能的影响。根据两点图像对比度和分辨率研究了这些光瞳函数的成像特性。可以看出，通过调整物体结构照明的相干状态以及适当选择光瞳函数，可以获得比艾里光瞳函数更高的分辨率。以类似的方式，也有可能在不过度降低图像分辨率的情况下提高图像对比度。
