Although the subject of optical design as a branch of applied physics is over one hundred years old, the use of aberration theory has changed considerably. Aberrations of Optical Systems covers elementary optics and aberration theory of various optical systems, including the use of nonaxially symmetric systems and diffractive optical elements in complex designs, such as head-up displays and the increasing use of scanning systems with laser illumination. The book provides the complete range of mathematical tools, formulae, and derivations needed for understanding the process of optical design and for planning optical design programs. While the treatment is mainly based on geometrical optics, some excursions into physical optics are made, particularly in connection with the problems of optical tolerances.

This book provides a clear, concise, and consistent exposition of what aberrations are, how they arise in optical imaging systems, and how they affect the quality of images formed by them. The emphasis of the book is on physical insight, problem solving, and numerical results, and the text is intended for engineers and scientists who have a need and a desire for a deeper and better understanding of aberrations and their role in optical imaging and wave propagation. Some knowledge of Gaussian optics and an appreciation for aberrations would be useful but is not required.

Aberration-Corrected Imaging in Transmission Electron Microscopy provides an introduction to aberration-corrected atomic-resolution electron microscopy imaging in materials and physical sciences. It covers both the broad beam transmission mode (TEM; transmission electron microscopy) and the scanning transmission mode (STEM; scanning transmission electron microscopy). The book is structured in three parts. The first part introduces the basics of conventional atomic-resolution electron microscopy imaging in TEM and STEM modes. This part also describes limits of conventional electron microscopes and possible artefacts which are caused by the intrinsic lens aberrations that are unavoidable in such instruments. The second part introduces fundamental electron optical concepts and thus provides a brief introduction to electron optics. Based on the first and second parts of the book, the third part focuses on aberration correction; it describes the various aberrations in electron microscopy and introduces the concepts of spherical aberration correctors and advanced aberration correctors, including correctors for chromatic aberration. This part also provides guidelines on how to optimize the imaging conditions for atomic-resolution STEM and TEM imaging. This second edition has been completely revised and updated in order to incorporate the very recent technological and scientific achievements that have been realized since the first edition appeared in 2010.

"This critical work considers the role played by elements that might be considered aberrational in a poet's oeuvre. With an introductory essay exploring the nature of aberration, these fourteen contributions investigate the work of major 20th-century poets from the U.S., Britain, Ireland, Australia and New Zealand"--Provided by publisher.

These are poems of family, of romantic hope and disappointment, of parenthood, and of grief that move from a childhood in Nebraska in which a father strides into a ripe wheat field; to the parks and parking lots of New York City, the interchangeable landscapes of suburban America, and the more sensual environment of secluded water; to little traveled parts of Africa and the Pacific where our customs and passions are refracted into shapes that are sometimes beautiful, sometimes grotesque. Terese Svoboda writes of a world in which the reassuring simplicity remembered from childhood is difficult to recover. Outside of this vision of the past, all present life seems an aberration--an existence where violence can supplant love, families break apart, a child dies. All Aberration received a starred review in Publishers Weekly, a lead in Contemporary Poetry 1986 and a Notable Book nomination by the American Library Association. It was written during stays at Yaddo, MacDowell and Ossabaw, and received the benefit of a Creative Artists Public Service grant in 1982. Its poems first appeared in such magazines as Harper's, The Nation, Paris Review, and Ploughshares.

The book is concerned with the theory, background, and practical use of transmission electron microscopes with lens correctors that can correct the effects of spherical aberration. The book also covers a comparison with aberration correction in the TEM and applications of analytical aberration corrected STEM in materials science and biology. This book is essential for microscopists involved in nanoscale and materials microanalysis especially those using scanning transmission electron microscopy, and related analytical techniques such as electron diffraction x-ray spectrometry (EDXS) and electron energy loss spectroscopy (EELS).

FBI analyst Kassidy Bishop is assigned to the "For You" killer's task force after a series of sadistic murders bearing the same signature arise in different parts of the country. The homicides are both calculated and savage, occurring in different states, but bearing the same signature: the words "for you" scribbled at each crime scene. The case chills Kassidy, bringing back memories of her own encounter with a violent criminal five years earlier. The stakes rise when the task force links the killer's signature to Kassidy. As more and more bodies turn up, Kassidy must delve into her past and the mysterious death of her twin sister, which holds the key to uncovering the killer's identity. The closer Kassidy comes to finding the killer, the closer she comes to a deadly confrontation that could cost her everything-including her own life.
