The spatial coherence wavelets theory provides more insight into the understanding of interference and diffraction
because they are the primary carriers of power and correlation of light. In this context, novel keys for analyzing the
physical properties of light are revealed by these wavelets, as discussed in the present work. Particularly, the bright and
the dark rays and related features as the energy flux vectors - parallel and anti-parallel to the Poynting vector, and the
transverse energy transference, provide insight into the mechanism of energy distribution of a wavefield after diffraction
and its dependence on spatial coherence properties of the field. These properties could be experimentally controlled by
modulating the spatial coherence of the light, offering new possibilities of technological applications in subjects
involving beam shaping.
