The volume of coherence has been usually defined as the volume of a right-angled cylinder whose base is the area of coherence and whose height is the coherence length. It is also the volume corresponding to one cell of phase space of photons.[2,3] We shall show in this paper that the former definition can be retained only in some particular cases whereas the latter one describes a greater variety of cases provided the notion of a cell of phase space is adequately specified.
