The principle of indirect imaging of stellar surfaces, based on spectroscopic and photometric rotation modulation is described, and application and results of Doppler imaging of spotted stars are presented. The common problem of regularization of the inverse problem for the interferometric and tomographic methods is discussed. The applicability of both methods to different phenomena of stellar activity is compared. It is concluded that space interferometry and tomographic imaging methods should be used to produce complementary results in order to have an access to phenomena of different temporal and spatial behavior.
