Book Synopsis Advanced Computing in Electron Microscopy by : Earl J. Kirkland

Download or read book Advanced Computing in Electron Microscopy written by Earl J. Kirkland. This book was released on 2020-03-09. Available in PDF, EPUB and Kindle. Book excerpt: This updated and revised edition of a classic work provides a summary of methods for numerical computation of high resolution conventional and scanning transmission electron microscope images. At the limits of resolution, image artifacts due to the instrument and the specimen interaction can complicate image interpretation. Image calculations can help the user to interpret and understand high resolution information in recorded electron micrographs. The book contains expanded sections on aberration correction, including a detailed discussion of higher order (multipole) aberrations and their effect on high resolution imaging, new imaging modes such as ABF (annular bright field), and the latest developments in parallel processing using GPUs (graphic processing units), as well as updated references. Beginning and experienced users at the advanced undergraduate or graduate level will find the book to be a unique and essential guide to the theory and methods of computation in electron microscopy.

Book Synopsis Advanced Techniques in Biological Electron Microscopy III by : J.K. Koehler

Download or read book Advanced Techniques in Biological Electron Microscopy III written by J.K. Koehler. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a continuation of two prior books on advanced electron microscope techniques. The purpose of this series has been to provide in depth analyses of methods which are considered to be at the leading edge of electron microscopic research procedures with applications in the biological sciences. The mission of the present volume remains that of a source book for the research practitioner or advanced student, especially one already well versed in basic electron optical methods. It is not meant to provide in troductory material, nor can this modest volume hope to cover the entire spectrum of advanced technology now available in electron microscopy. In the past decade, computers have found their way into many research laboratories thanks to the enormous increase in computing power and stor age available at a modest cost. The ultrastructural area has also benefited from this expansion in a number of ways which will be illustrated in this volume. Half of the contributions discuss technologies that either directly or indirectly make extensive use of computer methods.

Book Synopsis Computer Processing of Electron Microscope Images by : P. W. Hawkes

Download or read book Computer Processing of Electron Microscope Images written by P. W. Hawkes. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: Towards the end of the 1960s, a number of quite different circumstances combined to launch a period of intense activity in the digital processing of electron micro graphs. First, many years of work on correcting the resolution-limiting aberrations of electron microscope objectives had shown that these optical impediments to very high resolution could indeed be overcome, but only at the cost of immense exper imental difficulty; thanks largely to the theoretical work of K. -J. Hanszen and his colleagues and to the experimental work of F. Thon, the notions of transfer func tions were beginning to supplant or complement the concepts of geometrical optics in electron optical thinking; and finally, large fast computers, capable of manipu lating big image matrices in a reasonable time, were widely accessible. Thus the idea that recorded electron microscope images could be improved in some way or rendered more informative by subsequent computer processing gradually gained ground. At first, most effort was concentrated on three-dimensional reconstruction, particu larly of specimens with natural symmetry that could be exploited, and on linear operations on weakly scattering specimens (Chap. l). In 1973, however, R. W. Gerchberg and W. O. Saxton described an iterative algorithm that in principle yielded the phase and amplitude of the electron wave emerging from a strongly scattering speci men.

Book Synopsis Electron Energy-Loss Spectroscopy in the Electron Microscope by : R.F. Egerton

Download or read book Electron Energy-Loss Spectroscopy in the Electron Microscope written by R.F. Egerton. This book was released on 2013-03-09. Available in PDF, EPUB and Kindle. Book excerpt: to the Second Edition Since the first (1986) edition of this book, the numbers of installations, researchers, and research publications devoted to electron energy-loss spec troscopy (EELS) in the electron microscope have continued to expand. There has been a trend towards intermediate accelerating voltages and field-emission sources, both favorable to energy-loss spectroscopy, and sev eral types of energy-filtering microscope are now available commercially. Data-acquisition hardware and software, based on personal computers, have become more convenient and user-friendly. Among university re searchers, much thought has been given to the interpretation and utilization of near-edge fine structure. Most importantly, there have been many practi cal applications of EELS. This may reflect an increased awareness of the potentialities of the technique, but in many cases it is the result of skill and persistence on the part of the experimenters, often graduate students. To take account of these developments, the book has been extensively revised (over a period of two years) and more than a third of it rewritten. I have made various minor changes to the figures and added about 80 new ones. Except for a few small changes, the notation is the same as in the first edition, with all equations in SI units.
