Recent spectacular developments in optical cooling and trapping of atoms were preceded by the thorough investigation of interactions of the polarised laser beam with atoms in the sixties, seventies and eighties, in which the concept of atomic coherence played a prominent role. We review this concept in the context of spinor condensates and show that it provides one with a physically natural viewpoint with a link to a multitude of establshed techniques. In addition, access to two-body correlations in the spinor condensates through time-resolved measurement of atomic coherence is discussed.
