Optics is the branch of physics that studies the properties of light and its interaction with matter. It also involves design and construction of instruments required for studying the various phenomena related to light. This discipline usually includes ultraviolet, visible and infrared radiation. Light is an electromagnetic wave and it exhibits the behavior of wave as well as particle. To understand this dual nature optics has been further divided into ray optics and wave optics. It includes daily use objects and new technologies to study the properties of light such as lenses, mirrors, microscopes, fibre optics and lasers. This book provides significant information of this discipline to help develop a good understanding of optics and related fields. It includes contributions of experts and scientists which will provide innovative insights to the readers. The aim of this text is to present researches that have transformed this discipline and aided its advancement. It is appropriate for students seeking detailed information in the field of optics as well as experts.
