Abstract: Compare to the traditional geometric imaging, interferometric imaging in which complicated mathematical method is needed to reconstruct the original object is not intuitive. However, the angular resolution of an interferometric array, which is proportional to its maximum baseline, will not be limited by the size of individual telescope. The angular resolution of interferometric array is increasing rapidly. Now, the highest resolution is about milliarcsecond or even sub-milliarcsecond level, which makes interferomtric arrays the most powerful tools to study the multi-scale fine structures of the cosmology. In the history of interferometric imaging, it has incubated a lot of landmark scientific results. In future, interferometric imaging will be the key methods to explore some challenging objects, such as black hole, extraterrestial planets.
