One of the fastest growing applications is signal sensing, especially wavefront sensing for adaptive optics and fringe tracking for interferometry, which is important for long-baseline optical interferometry. The coherence time of the atmosphere is a highly variable parameter. Depending upon the high velocity wind, it varies from <1 ms to 0.1 s. The exposure times are to be selected accordingly, to maximize the signal-to-noise ratio, as well as to freeze the fringe pattern. A large-format photon-counting system, which is an essential tool in the application of optical interferometric imaging, allows accurate photon centroiding and provides the dynamic range needed for measurements of source characteristics. The advent of high-quantum efficiency photon-counting systems vastly increases the sensitivity of high-resolution imaging techniques. Such systems raise the hope of making diffraction-limited images of objects as faint as ~15–16 m_v (visual magnitude).
This book deals with the fundamentals of the important aspects of high-resolution imaging, such as electromagnetic radiations, particularly, optical wavelengths and their distortions due to optical elements and Earth’s atmosphere while passing through a detector; semiconductor physics; lasers; fiber optics; photon-detection process; photodetectors; charge-transfer devices; photon-counting devices in visible wavelength; radiation detectors in infrared wavelengths; and detecting systems for high energies.
Professor Swapan K. Saha has a strong interest in experimental physics, optical interferometry in particular, and has developed various instruments. He has taught observational astronomy, high-resolution imaging, aperture synthesis, adaptive optics, atmospheric science, and image processing at a couple of premiere institutes in India. Prof. Saha has delivered several invited and plenary talks at various national and international conferences and universities on these topics. Author of a few more books, he is on the editorial boards of the Asian Journal of Physics and the Journal of Optics (Springer) and has edited a book, 21st Century Astrophysics, as well as a special issue of the Asian Journal of Physics on astrophysics in 2004.
