Grating-based interferometers and their applications
Abstract
This dissertation is a theoretical and experimental study of space-invariant grating-based interferometers and their applications. A general, first-order theory is developed describing the basic properties of these interferometers which employ diffraction gratings both as beam splitters and as beam deflectors. Emphasis is on such aspects as fringe localization and the modulation transfer function exhibited by such systems when they are used for forming holograms. The analysis is based on a very generalized structural configuration and on illuminating sources of arbitrary spectrum and extension. The study stresses the great significance of the dispersive property of gratings to interferometry; it is indeed this property which makes such interferometers achromatic. An unlimited number of high contrast, high quality fringes can be obtained, regardless of the temporal and spatial coherence of the source.
