The amalgamation of optical physics and engineering has advanced the designing of equipment like cameras, microscopes, telescopes, etc. Optical physics and engineering are well known and established branches of optics. While optical physics is focused on the discovery and applications of phenomena related to optics; optical engineering is the field of study that entirely focuses on application of optics. This book elucidates the concepts and innovative models around prospective developments with respect to optical physics. The readers would gain knowledge that would broaden their perspective about the inter-disciplinary aspects of optical physics and optical engineering. Researchers and students in this field will be assisted by this book.
