The purpose of this book is to explain the basic principles of optics and image fomation particular to such lenses and optical systems. Much importance is placed on clear and detailed diagrams of contemporary equipment, and graphs of performance characteristics. The book begins with an explanation of visual perception, followed by sections on basic optics and image formation by representative systems; the design, the manufacture and testing of lenses andd optical systems; optical attachments, including filters and converters; the optics of a numbr of different types of camera; the projection of images; the anicllary and auxillary systems associated with image capture; and related optical and optp-electronic systems including fibre optics, LEDs and LCDs. The book is intended as a compact source of useful data, for anyone concerned with th visual communications industry, from secondary school pupils to professional camera users and euipment specialists. Sindey F Ray is Priniciple Lecturer in Photographic Sciences and Electronic Imaging at the University of Westminster. His other book for Focal Press, Applied photographic Optics has been acclaimed as the definitive work on the subject. he is also the co-author of The Manual of Photography.
