Professor S. K. Saha is with the Indian Institute of Astrophysics in Bangalore, India. He has spent one year (1988-89) at the Observatoire de la Cote d'Azur (formerly C.E.R.G.A) in Caussols, France. During this year he conducted research on the high angular features of stars, using the long baseline topical interferometer with a pair of 1.5 meter telescopes. He has a strong interest in Experimental Physics and has developed various equipment in the area. He is the author of the book Diffraction-Limited Imaging with Large and Moderate Telescopes (World Scientific, 2007). Another book, 21st Century Astrophysics (Anita Publications, 2005, with V. K. Rastogi (Ed.)) was brought out to commemorate Einstein's "Year of Miracles," which contains a set of articles written by reputed scientists working at the various laboratories across the Globe. Saha has edited a special issue of Asian J. Physics on 'Astrophysics" in 2004.

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, properties, and optical effects of turbulence in the Earth's atmosphere, techniques developed to overcome image degradation. Studded with more than one hundred and fifty illustrations and tens of footnotes, it addresses the basic tricks of trade, current trend, motivation, methods, and path to future promise of true interferometry both from the ground and space. Also discussed are the technical challenge involved, such as beam transportation and recombination, detecting fringes using modern sensors, and image synthesis. Astronomical science that benefits from aperture synthesis imaging are highlighted as well. - Newsletter
