This article reviews the field of interferometry. It begins by outlining the fundamentals of two-beam and multiple-beam interference. The rest of the article discusses the applications of interferometry for measurement of length, optical testing, fringe analysis, interference microscopy, interferometric sensors, interference spectroscopy, nonlinear interferometers, interferometric imaging, space-time and gravitation, holographic interferometry, Moiré techniques, and speckle interferometry. Each section provides a referenced (and cross-referenced) overview of the application area.
