Singularities in Speckled Speckle: Statistics [PDF]
, 2008 Random optical fields with two widely different correlation lengths generate far field speckle spots that are themselves highly speckled. We call such patterns speckled speckle, and study their critical points (singularities and stationary points) using analytical theory and computer simulations.

New methods for masked-aperture and speckle interferometry [PDF]
Publ.Astron.Soc.Pac. 111 (1999) 595, 1999 Diffraction-limited images can be obtained with a large optical telescope using interferometry. One such method for objects of sufficient brightness is non-redundant masking (NRM), in which observations are made through a pupil mask that contains an array of small holes. However, NRM only uses a small fraction of the available light.
