The coherence and polarization are two closely related aspects in statistical optics, which play an important role on properties of the beam transmission. The basic theory of coherence and polarization, specially the unified theory of coherence and polarization, is introduced, which is based on the cross-spectral density matrix. Some current research focus of this field are summarized and analyzed, such as the propagation changes of polarization properties, the scattering theory of partially coherent beams, the spectral degree of cross-polarization and three-dimensional stochastic electromagnetic beams. The issues about the theory of coherence and polarization are summarized and prospected.
