Modified astronomical speckle interferometry “speckle masking”

Optics Communications, 1977
Abstract A simple method (speckle masking) for the reconstruction of real images from astronomical speckle photographs is described. This method is applicable to a restricted class of objects that includes double stars. Double stars are the object most frequently observed with speckle interferometry techniques. Certain other kinds of objects can also

Fluorescent Speckle Microscopy

Cold Spring Harbor Protocols, 2011
INTRODUCTIONFluorescent speckle microscopy (FSM) is a live imaging and quantitative measurement technique used for analyzing motion and turnover of macromolecular assemblies in vivo and in vitro. It differs from related imaging techniques such as photobleaching and photoactivation in its use of substantially lower concentrations of fluorescently ...

Stellar speckle interferometry

Physics Bulletin, 1975
Stellar speckle interferometry is a technique for obtaining diffraction-limited resolution of stellar objects despite the presence of the turbulent atmosphere which limits the resolution of conventional long-exposure pictures to approximately one arc second.
