Optics Essentials

The field of optics is the study of light in its entire spectrum like high energy X-rays, ultraviolet, visible, infrared light, low energy radio waves, etc. and their individual interactions with matter. Optical phenomena are generally approached from the domains of physical and geometric optics. The classical electromagnetic description of light as well as the quantum mechanical approach to light together creates a comprehensive framework of optical dynamics. It has prominent applications in engineering, photography and medicine. The objective of this book is to give a general view of the different areas of study within the field of optics and their applications. It also presents researches and studies performed by experts across the globe. It is meant for students and researchers who are looking for an elaborate reference text on optics.
