The present “state of the art” and the path to future progress in high-spatial-resolution
imaging interferometry is reviewed. The review begins with a treatment of the fundamentals …

This book deals with the fundamentals of stellar interferometry with emphasis on aperture
synthesis using sparse array of telescopes particularly at optical/IR wavelengths, the origin …

A new high-resolution radio spectropolarimeter instrument operating in the frequency range
of 15–85 MHz has recently been commissioned at the Radio Astronomy Field Station of the …

It was a year in which some topics selected themselves as important through the sheer
numbers of papers published. These include the connection (s) between galaxies with …

Speckle Imaging based on triple correlation is a very efficient image reconstruction
technique which is used to retrieve Fourier phase information of the object in presence of …

Speckle interferometric technique is used to record a series of short exposure images of
several close binary stars with sub-arcsecond separation through a narrow band filter …

Experiments are performed to determine the coherence properties of wave fields, produced

(VBT), at Vainu Bappu Observatory (VBO), Kavalur, India, has been designed and …

The speckle imaging is a photographic technique that resolves objects viewed through
severely distorted media. The results are insensitive to the errors caused by apparent size of …

Single aperture interferometry by means of speckle imaging has made inroads in several
important fields in astrophysics. In recent years, the adaptive optics system at the telescope …
