Optical engineering is one of the most exciting fields of development for engineering in the 20th century. After fibre optic communications, non-contact inspection and laster bar code readers it is one of the major areas in employment for engineers. This text is for engineers who have made the move to the optical regime but with little or no direct experience or understanding of the subject. Unlike traditional optical engineering texts, Mastering Optics does not assume even a basic understanding of the subject; in fact it is aimed at a multi-disciplined readership with the purpose of enabling the reader to master the vocabulary of optical engineering. All of the main concepts are addressed through the major applications, rather than as subjects in themeselves. Mathematical treatments are kept to an absolute minimum with the emphasis on understnading techniques and jargon rather than derivations from first principles.
