Glow discharge optical emission spectroscopy (GDOES) is an essential technique for the direct analysis of bulk solids, for elemental surface analysis and for the depth profiling of thin films and industrial coatings. The technique has shown rapid growth in numbers of instruments, in breadth of applications, in improved quantification in recent years and is now a recognised technique within the ISO, with two international standards. Glow Discharge Optical Emission Spectroscopy: A Practical Guide takes the reader on a journey through instrument operation, sample preparation, analysis, and reporting results. It follows two sets of samples through the whole process of analysis, brass samples for bulk analysis, and zinc-coated steel for depth profiling. Procedures are consistent with ISO standards and each step is loaded with hands-on tips and theoretical insight. The book also includes unique data tables on spectral interferences, molecular bands, self-absorption and relative sputtering rates.This book is designed for those using or managing GDOES instruments and for students interested in learning the technique from a hands-on perspective. It is also an invaluable aid to those considering the purchase of a GDOES instrument, or those using GDOES results, to understand in detail how the technique works and what is involved in maintaining the instrument and achieving high quality results.
This text is intended to provide an in-depth, self-contained, treatment of optical waveguide theory. We have attempted to emphasize the underlying physical processes, stressing conceptual aspects, and have developed the mathematical analysis to parallel the physical intuition. We also provide comprehensive supplementary sections both to augment any deficiencies in mathematical background and to provide a self-consistent and rigorous mathematical approach. To assist in. understanding, each chapter con- centrates principally on a single idea and is therefore comparatively short. Furthermore, over 150 problems with complete solutions are given to demonstrate applications of the theory. Accordingly, through simplicity of approach and numerous examples, this book is accessible to undergraduates. Many fundamental topics are presented here for the first time, but, more importantly, the material is brought together to give a unified treatment of basic ideas using the simplest approach possible. To achieve such a goal required a maturation of the subject, and thus the text was intentionally developed over a protracted period of the last 10 years.
""This is a very entertaining collection of optical illusions, full of pictures that will leave you scratching your head as you try to figure out how they've fooled you. There are loads of them, and it's the best optical illusion book I've come across."" - Bertass Reviews Anything/World of Children's BooksAn image on a page appears to vibrate, a face gradually disappears, and a puzzling cat makes an appearance in this feast of fascinating optical tricks. Children and adults can discover the fascinating intersection of art, science, and magic in a series of geometric illusions, delusions, distortion effects, and other impossible images.Designed and drawn by a famous puzzle maker, the book is intended to perplex readers, to excite their sense of wonder, and to encourage them to question the nature of reality. The optical illusions, which combine visual interest with elements of psychology and recreational logic, include many original illusions as well as new adaptations of lesser-known visual tricks. Each of the images is accompanied by a simple commentary that explains how it works.
