It is now well-established that a variety of singularities can be characterized and observed in optical wavefields. It is also known that these phase singularities, polarization singularities and coherence singularities are physically related, but the exact nature of their relati

The interference pattern observed in Young's double-slit experiment is intimately related to the statistical correlations of the waves emitted by the slits. As the waves in the slits become more correlated, the visibility of the interference pattern increases. Here, we experiment

When spatially coherent radiation is diffracted by a crystalline object, the field is scattered in specific directions, giving rise to so-called von Laue patterns. We examine the role of spatial coherence in this process. Using the first-order Born approximation, a general analyt

If the state of polarization of a monochromatic light beam is changed in a cyclical manner, the beam acquires¿in addition to the usual dynamic phase¿a geometric phase. This geometric or Pancharatnam¿Berry phase equals half the solid angle of the contour traced out on the Poincaré
