Available in PDF, EPUB and Kindle. Book excerpt: This book features reviews by leading experts on the methods and applications of modern forms of microscopy. The recent awards of Nobel Prizes awarded for super-resolution optical microscopy and cryo-electron microscopy have demonstrated the rich scientific opportunities for research in novel microscopies. Earlier Nobel Prizes for electron microscopy (the instrument itself and applications to biology), scanning probe microscopy and holography are a reminder of the central role of microscopy in modern science, from the study of nanostructures in materials science, physics and chemistry to structural biology. Separate chapters are devoted to confocal, fluorescent and related novel optical microscopies, coherent diffractive imaging, scanning probe microscopy, transmission electron microscopy in all its modes from aberration corrected and analytical to in-situ and time-resolved, low energy electron microscopy, photoelectron microscopy, cryo-electron microscopy in biology, and also ion microscopy. In addition to serving as an essential reference for researchers and teachers in the fields such as materials science, condensed matter physics, solid-state chemistry, structural biology and the molecular sciences generally, the Springer Handbook of Microscopy is a unified, coherent and pedagogically attractive text for advanced students who need an authoritative yet accessible guide to the science and practice of microscopy.
Download or read book Fourier Ptychographic Microscopy for High resolution Large Field of View Imaging written by Eugene Egbert Fouche and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fourier ptychographic microscopy (FPM) is an imaging technique which overcomes the limitationsof conventional microscopy to construct high-resolution, large field of view (FOV) images of a sample. Usually, there is a trade-off between resolution and field of view, but FPM allows samples to be viewed at a high resolution, while maintaining a large FOV. FPM is a computational imaging technique, where multiple low-resolution images of a sample are used to reconstruct the sample at a much higher resolution. The sample is illuminated from various angles, and a low-resolution image is captured for each illumination angle using a lens with a low numerical aperture (NA). The low NA lens has a large FOV, and the various illumination angles allows one to obtain information about the smaller sample features. This allows one to reconstruct a high-resolution, large FOV image of the sample using an iterative reconstruction algorithm. An LED array is typically used to provide the angularly varying illumination. Many real-world samples alter both the amplitude and the phase of the light that is transmitted through them. However, only the intensity can be measured on a camera, and the phase information is lost. In FPM, the various sample images allows one to recover the phase of the sample, as well as the amplitude. This can be used to correct for errors in the imaging setup, and also enhances the contrast when viewing biological samples.In this thesis, the theoretical framework behind FPM is explained, and simulations are performed to investigate the effect of the LED array size and the number of iterations of the reconstruction algorithm on the quality of the reconstructed sample. The error correction (defocus aberration) is also investigated. Two setups are constructed to investigate FPM experimentally. The first setup uses an LED array, and is used to image known calibration targets and real-world biological samples. This setup is also adapted to perform polarization-sensitive FPM (pFPM) on birefringent mineral samples to image the different crystal domains in the samples. The second setup uses a continuous wave laser as the light source and a 2-dimensional spatial light modulator (2D-SLM) to provide the angularly varying illumination. This setup is used to image a known calibration target. Both setups are characterised, and their performance is compared to illustrate their suitability for different imaging scenarios."--ENGLISH ABSTRACT.

Download or read book Proximal Algorithms written by Neal Parikh and published by Now Pub. This book was released on 2013-11 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proximal Algorithms discusses proximal operators and proximal algorithms, and illustrates their applicability to standard and distributed convex optimization in general and many applications of recent interest in particular. Much like Newton's method is a standard tool for solving unconstrained smooth optimization problems of modest size, proximal algorithms can be viewed as an analogous tool for nonsmooth, constrained, large-scale, or distributed versions of these problems. They are very generally applicable, but are especially well-suited to problems of substantial recent interest involving large or high-dimensional datasets. Proximal methods sit at a higher level of abstraction than classical algorithms like Newton's method: the base operation is evaluating the proximal operator of a function, which itself involves solving a small convex optimization problem. These subproblems, which generalize the problem of projecting a point onto a convex set, often admit closed-form solutions or can be solved very quickly with standard or simple specialized methods. Proximal Algorithms discusses different interpretations of proximal operators and algorithms, looks at their connections to many other topics in optimization and applied mathematics, surveys some popular algorithms, and provides a large number of examples of proximal operators that commonly arise in practice.
