This book was released on 2012 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Imperfections in image formation, called aberrations, often preclude microscopes from reaching diffraction-limited resolution. Aberrations can be caused either by the microscope itself or by the sample and can be compensated for by using an active element integrated into the beam path which is functioning as a corrector. The optimal settings for this corrector need to be determined without excessive damage to the sample. In particular, for sensitive biological samples, the potential gain for signal and/or resolution needs to be weighed against sample damage. Here I present the development of a special type of optical coherence microscopy (called deep-OCM), which allows the precise determination of the average rat brain refractive index in vivo. The conclusion is that two-photon microscopy is affected by optical aberrations in this sample starting at depths around 200 μm. Deep-OCM is well suited for imaging myelinated nerve fibers. Individual fibers can be visualized in the living brain in unprecedented depths beyond 300 μm. In the second part of this thesis I describe the development and testing of an auto-focuser and auto-stigmator (called MAPFoSt) for a scanning electron microscope to ensure optimal imaging quality after switching samples or during long acquisition series. MAPFoSt determines the three focus and stigmation parameters from only two test images.

Download or read book Transmission Electron Microscopy written by Ludwig Reimer and published by Springer. This book was released on 2013-11-11 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to outline the physics of image formation, electron specimen interactions and image interpretation in transmission electron mic roscopy. The book evolved from lectures delivered at the University of Munster and is a revised version of the first part of my earlier book Elek tronenmikroskopische Untersuchungs- und Priiparationsmethoden, omitting the part which describes specimen-preparation methods. In the introductory chapter, the different types of electron microscope are compared, the various electron-specimen interactions and their applications are summarized and the most important aspects of high-resolution, analytical and high-voltage electron microscopy are discussed. The optics of electron lenses is discussed in Chapter 2 in order to bring out electron-lens properties that are important for an understanding of the function of an electron microscope. In Chapter 3, the wave optics of elec trons and the phase shifts by electrostatic and magnetic fields are introduced; Fresnel electron diffraction is treated using Huygens' principle. The recogni tion that the Fraunhofer-diffraction pattern is the Fourier transform of the wave amplitude behind a specimen is important because the influence of the imaging process on the contrast transfer of spatial frequencies can be described by introducing phase shifts and envelopes in the Fourier plane. In Chapter 4, the elements of an electron-optical column are described: the electron gun, the condenser and the imaging system. A thorough understanding of electron-specimen interactions is essential to explain image contrast.

Available in PDF, EPUB and Kindle. Book excerpt: Academic and industrial research around polymer-based colloids is huge, driven both by the development of mature technologies, e.g. latexes for coatings, as well as the advancement of new materials and applications, such as building blocks for 2D/3D structures and medicine. Edited by two world-renowned leaders in polymer science and engineering, this is a fundamental text for the field. Based on a specialised course by the editors, this book provides the reader with an invaluable single source of reference. The first section describes formation, explaining basic properties of emulsions and dispersion polymerization, microfluidic approaches to produce polymer-based colloids and formation via directed self-assembly. The next section details characterisation methodologies from microscopy and small angle scattering, to surface science and simulations. The final chapters close with applications, including Pickering emulsions and molecular engineering for materials development. A comprehensive guide to polymer colloids, with contributions by leaders in their respective areas, this book is a must-have for researchers and practitioners working across polymers, soft matter and chemical and molecular engineering.
