Abstract

The research history about Doppler imaging of stellar surface structure was looked back, and its application in the late-type star with sun-like activity was reviewed. The international development status about Doppler imaging technique of starspot structure on stellar surface was introduced, the basic principle about this technique was shown, and its demands on instrument, observation and object were discussed. Finally, we give a prospects for this kind of research work in future.
