| 中文摘要: |
| 远场显微成像是近年来的研究热点,而微球颗粒在远场成像中具有一定的放大作用。针对这种现象,通过对微球颗粒的分离,对单个微球颗粒的成像特性进行了理论研究。实验表明,利用一定尺寸的二氧化硅微球颗粒,可以使远场显微镜的分辨率提高一倍。在尼康显微镜下,利用普通卤素灯光源、二氧化硅和相应的增强介质,对1200线的光栅实现了近一倍的放大成像效果,证实了微球颗粒的远场显微成像能力。 |

| The far-field super-resolution imaging is a hot spot in the research.It is found that the microsphere played an important role in the far-field imaging. We design an experiment to realize de-aggregation of microsphere, and theoretically study imaging characteristics of single microsphere. According to the experimental research, we can double the resolution of far-field microscope by utilizing a specific scale of silica microsphere. By using the Nikon microscope with the halide lamp under the silica microsphere and relevant enhanced-medium, we double the imaging effect of a 1200 line optical grating,and it shows the far-field imaging efficiency of microsphere. |
