This book compiles recent studies on interferometry and its applications in science and technology. It is intended as an up-to-date reference of theoretical and experimental aspects of interferometry and their applications. The book is divided in two sections. The first one is an overview of different interferometry techniques and their general applications. Chapter 1 is concentrated on the classical field interferometry. This chapter describes and explains the structures of different type of fiber interferometers, and the standard methods for signal recovering
