Novel keys for analyzing physical features of light

摘要

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.
