Speckle Decorrelation and Dynamic Range in Speckle Noise Limited Imaging [PDF]
arXiv, 2003 The useful dynamic range of an image in the diffraction limited regime is usually limited by speckles caused by residual phase errors in the optical system forming the image. The technique of speckle decorrelation involves introducing many independent realizations of additional phase error into a wavefront during one speckle lifetime, changing the ...

PISCO2: the new speckle camera of the Nice 76-cm refractor
, 2014 We present the new speckle camera PISCO2 made in 2010-2012, for the 76-cm refractor of C\^ote d'Azur Observatory. It is a focal instrument dedicated to the observation of visual binary stars using high angular resolution speckle interferometry techniques

Information retrieval from holographic interferograms: Fundamentals and problems [PDF]
Holographic interferograms can contain large amounts of information about flow and temperature fields. Their information content can be very high because they can be viewed from many different directions. This multidirectionality, and fringe localization
