During the last two decades, optical stellar interferometry has become an important tool in astronomical investigations requiring spatial resolution well beyond that of traditional telescopes. This book, first published in 2006, was the first to be written on the subject. The authors provide an extended introduction discussing basic physical and atmospheric optics, which establishes the framework necessary to present the ideas and practice of interferometry as applied to the astronomical scene. They follow with an overview of historical, operational and planned interferometric observatories, and a selection of important astrophysical discoveries made with them. Finally, they present some as-yet untested ideas for instruments both on the ground and in space which may allow us to image details of planetary systems beyond our own.
An Introduction to Optical Stellar Interferometry
This is the first book on optical stellar interferometry. It covers the history, theory and future uses of interferometeric techniques. It discusses ideas and instruments used in interferometry for advanced students in physics, optics, and astronomy with an interest in astronomical interferometry.

Over the last decade, stellar interferometry has developed from a specialist tool to a mainstream observing technique, attracting scientists whose research benefits from milliarcsecond angular resolution. Stellar interferometry has become part of the astronomer’s toolbox, complementing single-telescope observations by providing unique capabilities that will advance astronomical research. This carefully written book is intended to provide a solid understanding of the principles of stellar interferometry to students starting an astronomical research project in this field or to develop instruments and to astronomers using interferometry but who are not interferometrists per se. Illustrated by excellent drawings and calculated graphs the imaging process in stellar interferometers is explained starting from first principles on light propagation and diffraction, wave propagation through turbulence is described in detail using Kolmogorov statistics, the impact of turbulence on the imaging process is discussed both for single telescopes and for interferometers, instrumental techniques like beam combination and array layout are described, and the requirements for delay lines are derived, visibility measurements (modulus and phase) through turbulence are analyzed and limitations are quantified, correction methods (fringe tracking and adaptive optics) are presented, discussing closed loop operation with a dual feed system. The book closes with examples of contemporary stellar interferometers and useful appendices on the Fourier transform and atmospheric transmission bands.
