Book excerpt: Among the various types of x-ray microscopes that have been demonstrated, the holographic microscope has had the largest gap between promise and performance. The difficulties of fabricating x-ray optical elements have led some to view holography as the most attractive method for obtaining the ultimate in high resolution x-ray micrographs; however, we know of no investigations prior to 1987 that clearly demonstrated submicron resolution in reconstructed images. Previous efforts suffered from problems such as limited resolution and dynamic range in the recording media, low coherent x-ray flux, and aberrations and diffraction limits in visible light reconstruction. We have addressed the recording limitations through the use of an undulator x-ray source and high-resolution photoresist recording media. For improved results in the readout and reconstruction steps, we have employed metal shadowing and transmission electron microscopy, along with numerical reconstruction techniques. We believe that this approach will allow holography to emerge as a practical method of high-resolution x-ray microscopy. 30 refs., 4 figs.

Download or read book X Ray Microscopy III written by Alan G. Michette and published by Springer. This book was released on 2013-06-05 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth of interest and research activity in X -ray microscopy is reflected in the increasing size and scope of a related series of international conferences, the latest of which (XRM90) was held at King's College London (3-7 September 1990) with over 130 delegates. Previous conferences in Gottingen and Brookhaven resulted in books in the Springer Series in Optical Sciences, and this volume, the proceedings of XRM90, maintains this tradition. Because of the large number of papers their lengths were strictly limited and, while most papers can be directly identified with conference presentations, in a few cases those on similar topics by the same authors have been combined into a longer paper to allow better use of the space. The book is divided into six parts, with Parts IT-VI covering the major areas of interest at the conference. In Part 1 are two overviews; Ron Burge presented the opening paper of the conference, while the closing, summary, contrlbution by Janos Kirz is included here as a comprehensive introduction to the remainder of the book. Part IT covers developments in X -ray sources and optics. The high average brightnesses of synchrotron radiation sources have made many applications pos sible, while the more convenient, laboratory-based, plasma sources offer much promise for the future. Several contributions report significant advances in X-ray optics, which must clearly continue fully to exploit the latest sources.

This book was released on 2013-11-09 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on presentations to the International Conference of X-Ray Micro scopy and Spectromicroscopy, XRM 96, which took place in Wiirzburg, August 19- 23, 1996. The conference also celebrated the lOOth anniversary of the discovery of X rays by Wilhelm Conrad Rontgen on November 8, 1895, in Wiirzburg. This book contains state-of-the-art reviews and up-to-date progress reports in the field of X-ray microscopy and spectromicroscopy, including related new X-ray optics and X-ray sources. It reflects the lively activities within a relatively new field of science which combines the development of new instruments and methods with their applications to numerous topical scientific questions. The applications range from biological and medical topics, colloid physics, and soil sciences to solid-state physics, material sciences, and surface sciences. Their variety demonstrates the interdisci plinary and cooperative character of this field and the growing demand for micro scopic and spectromicroscopic information on the nanometer scale and under specific sample conditions, for example in wet (natural) surroundings or on a solid surface.

Download or read book X Ray Microscopy II written by David Sayre and published by Springer. This book was released on 2013-06-05 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on papers presented at the International Symposium on X-Ray Microscopy held at Brookhaven National Laboratory, Upton NY, August 31-September 4, 1987. Previous recent symposia on the sub ject were held in New York in 1979, Gottingen in 1983 and Taipei in 1986. Developments in x-ray microscopy continue at a rapid pace, with im portant advances in all major areas: x-ray sources, optics and components, and microscopes and imaging systems. Taken as a whole, the work pre sented here emphasizes three major directions: (a) improvements in the capability and image-quality of x-ray microscopy, expressed principally in systems attached to large, high-brightness x-ray sources; (b) greater access to x-ray microscopy, expressed chiefly in systems employing small, often pulsed, x-ray sources; and (c) increased rate of exploration of applications of x-ray microscopy. The number of papers presented at the symposium has roughly dou bled compared with that of its predecessors. While we are delighted at this growth as a manifestation of vitality and rapid growth of the field, we did have to ask the authors to limit the length of their papers and to submit them in camera-ready form. We thank the authors for their con tributions and for their efforts in adhering to the guidelines on manuscript preparation.

Download or read book X ray Holographic Microscopy Using the Atomic force Microscope written by and published by . This book was released on 1993 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present authors have been seeking for some time to improve the resolution of holographic microscopy and have engaged in a continuing series of experiments using the X1A soft x-ray undulator beam line at Brookhaven. The principle strategy for pushing the resolution lower in these experiments has been the use of polymer resists as x-ray detectors and the primary goal has been to develop the technique to become useful for examining wet biological material. In the present paper the authors report on progress in the use of resist for high-spatial-resolution x-ray detection. This is the key step in in-line holography and the one which sets the ultimate limit to the image resolution. The actual recording has always been quite easy, given a high-brightness undulator source, but the difficult step was the readout of the recorded pattern. The authors describe in what follows how they have built a special instrument: an atomic force microscope (AFM) to read holograms recorded in resist. They report the technical reasons for building, rather than buying, such an instrument and they give details of the design and performance of the device. The authors also describe the first attempts to use the system for real holography and the authors show results of both recorded holograms and the corresponding reconstructed images. Finally, the authors try to analyze the effect that these advances are likely to have on the future prospects for success in applications of x-ray holography and the degree to which the other technical systems that are needed for such success are available or within reach.

Download or read book X Ray Microscopy written by G. Schmahl and published by Springer. This book was released on 2013-04-17 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray microscopy fills a gap between optical and electron microscopy. Using soft x-rays, a resolution higher than with visible light can be obtained. In comparison to electron microscopy, thick, wet, unstained specimens can be examined. This is especially advantageous for biological applications. The intense synchrotron radiation of electron storage rings and the de velopment of optical elements for soft x-rays render x-ray microscopy feasi ble for basic research. Wider applications will be possible in the future with the development of laboratory x-ray sources and microscopes. In 1979 a conference on x-ray microscopy was organized by the New York Academy of Sciences and in 1981 a symposium on high resolution soft x-ray optics was held at Brookhaven. The present volume contains the contributions to the sympos i um "X-Ray Microscopy", organ i zed by the Akademie der Wi ssen schaften in Gottingen in September 1983. In their capacity as conference chairmen, the editors would like to thank the Akademie der Wissenschaften, especially Prof. H.G. Wagner, Secretary of the Academy, and Mr. J. Pfahlert for organizing the symposium. We are in debted to the Stiftung Volkswagenwerk for financial support. The symposium was held at the Max-Planck-Institut fUr Stromungsforschung.

Download or read book Modern Microscopies written by P.J. Duke and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: For several decades the electron microscope has been the instrument of choice for the examination of biological structures at high resolution. Biologists have be come familiar with the techniques and pitfalls of sample preparation and with the interpretation of the images obtained. The purpose of this book is to introduce the biologist to a number of new imaging techniques that are now becoming avail able to supplement and even extend the information that can be obtained from the now-traditional electron microscope. Some of these techniques are still at the experimental stage, while others, such as cryoelectron microscopy and confocal optical microscopy, are at advanced stages of development and are already avail able commercially. This book represents a first attempt to quantify the progress made by bring ing together, in one volume, an account of the technical bases and the future potentials of the various techniques. Although the content is primarily aimed at biologists, microscopists in other fields should also find the information of interest and use. All the chapters are written by leading experts who are at the forefront of these exciting developments. About half the book is concerned with x-ray microscopy; the editors make no apology for this since they are both intimately involved with developments associated with this field and therefore view it, perhaps with bias, as being of the utmost importance.
