An interferometer is a device that splits a beam of light into two beams. In this book, the most prominent active interferometers are discussed from a research point of view focusing on three variants. Among the many topics of research included in this book are: results of adaptive interferometers operation based on photorefractive crystals and the effect of the non-steady state photo-electromotive force, a reanalysis of the framework of the 'magnetic' components of gravitational waves, the development of a real-time in situ surface height measuring system based on phase shifting...

This book depicts a knowledge odyssey guided by engineering and physics concepts that are honed into pathways that help define certain parts of the natural world as we believe it to be. Stark differences are drawn from our interface with this virtual world that societies have concocted throughout the eons of time. This odyssey travels from the microcosm to the macrocosm; from infinity to infinity.
