结果表明，基于手机的显微镜的分辨率可以提高与使用的毫米级球透镜与指数n=1.85放置在接触的荧光（FL）的染料掺杂的微球表示的对象。使用通过这种球透镜的虚拟成像，在约0.1 × 0.1 mm2的视场内实现了从约35 µm到约2 µm的分辨率提高。通过优化接触球透镜的参数，可以期望进一步提高分辨率和视场，这可以导致所提出的技术在移动的生物医学成像中的广泛应用。
It is shown that the resolution of cellphone-based microscopy can be improved with the use of millimeter-scale ball lenses with index n=1.85 placed in contact with fluorescent (FL) objects represented by dye-doped microspheres. Using the virtual imaging through such ball lenses, the resolution improvement from ~35 µm to ~2 µm is achieved over a field-of-view of about 0.1 × 0.1 mm2. Further improvement of resolution and field-of-view can be expected with optimization of parameters of the contact ball lenses that can lead to wide applications of the proposed technology in mobile biomedical imaging.
