Interferometry

This is an extensively revised, updated and enlarged edition of Dr Steel's popular textbook on interferometry. The book provides a general treatment that brings together the many different applications of the interference of electromagnetic waves. The applications can cover precise measurement of length, the testing of optical components against a computed hologram, measurements of atmospheric pollution by infrared spectroscopy, and the measurement of the size of visible stars. These apparently unrelated methods have a common theory, which the book presents and extends to each main field of application.
