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 optical speckle interferometer for use at the 2.34 meter Vainu Bappu Telescope
(VBT), at Vainu Bappu Observatory (VBO), Kavalur, India, has been designed and …

We have presented the basic mathematical treatment of interferometry in the optical domain.
Its applications in astronomical observations using both the single aperture, as well as the …

In general, an image degraded by blurring or defocusing is restored by deconvolution using
a substantially constant PSF. However, in the case of a confocal laser microscope, there is a …

Understanding the stars is the bedrock of modern astrophysics. Stars are the source of life.
The chemical enrichment of our Milky Way and of the Universe with all elements heavier …

This article begins with the discussions on the formation of speckles in the case of non-
coherent quasi monochromatic source and of ways to detect them. Prior to this, a brief …
