Download or read book Adaptive Optics for Vision Science written by Jason Porter and published by John Wiley & Sons. This book was released on 2006-06-12 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leading experts present the latest technology and applications in adaptive optics for vision science Featuring contributions from the foremost researchers in the field, Adaptive Optics for Vision Science is the first book devoted entirely to providing the fundamentals of adaptive optics along with its practical applications in vision science. The material for this book stems from collaborations fostered by the Center for Adaptive Optics, a consortium of more than thirty universities, government laboratories, and corporations. Although the book is written primarily for researchers in vision science and ophthalmology, the field of adaptive optics has strong roots in astronomy. Researchers in both fields share this technology and, for this reason, the book includes chapters by both astronomers and vision scientists. Following the introduction, chapters are divided into the following sections: * Wavefront Measurement and Correction * Retinal Imaging Applications * Vision Correction Applications * Design Examples Readers will discover the remarkable proliferation of new applications of wavefront-related technologies developed for the human eye. For example, the book explores how wavefront sensors offer the promise of a new generation of vision correction methods that can deal with higher order aberrations beyond defocus and astigmatism, and how adaptive optics can produce images of the living retina with unprecedented resolution. An appendix includes the Optical Society of America's Standards for Reporting Optical Aberrations. A glossary of terms and a symbol table are also included. Adaptive Optics for Vision Science arms engineers, scientists, clinicians, and students with the basic concepts, engineering tools, and techniques needed to master adaptive optics applications in vision science and ophthalmology. Moreover, readers will discover the latest thinking and findings from the leading innovators in the field.

Download or read book Liquid Crystal Based Electro Optic Diffractive Spectacle Lenses and Low Operating Voltage Nematic Liquid Crystals written by and published by . This book was released on 2005 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diffractive optical elements in which discrete phase levels are used to approximate a continuous blaze profile offer the advantage over conventional refractive optics in that they are essentially planar structures and thus consume very little space. Furthermore, it has been shown that switchable diffractive elements can be fabricated using electro-optic materials such as inorganic electro-optic crystals and liquid crystals. In this work, liquid crystal diffractive lenses are investigated for their possible use as switchable spectacle lenses, an alternative to current bifocal and progressive lens technologies. In these lenses, discrete, rotationally symmetric electrodes are used to generate the stepped phase levels of a diffractive lens in a 5 micrometer layer of nematic liquid crystal. Near theoretical diffraction efficiencies are reported for both 2 and 4 phase level lenses and it is shown that the inter-electrode gap is a critical design parameter for achieving these values. For the 4 level lenses the near theoretical values are achieved by implementing a novel, multi-level electrode structure that eliminates the inter-electrode gap while maintaining electrical isolation between adjacent electrodes. Additionally, the results of a study aimed at reducing the operating voltages of nematic liquid crystal are also included. In this study, colorless molecular dopants with high dipole moments are added to commercial nematic liquid crystal mixtures for the purpose of increasing dielectric anisotropy, upon which the threshold voltage is inversely dependent. While a reduction in threshold voltage is observed it is determined that a reduction in order parameter is the cause. Quantum-chemical analysis of the dopant molecules indicate that the structures are too rigid for introduction into a liquid crystal host and a new, less rigid structure is proposed.

Download or read book Liquid Crystals written by Pawel Pieranski and published by John Wiley & Sons. This book was released on 2021-08-31 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book on liquid crystals reports on the new perspectives that have been brought about by the recent expansion of frontiers and overhaul of common beliefs. First, it explores the interaction of light with mesophases, when the light or matter is endowed with topological defects. It goes on to show how electrophoresis, electro-osmosis and the swimming of flagellated bacteria are affected by the anisotropic properties of liquid crystals. It also reports on the recent progress in the understanding of thermomechanical and thermohydrodynamical effects in cholesterics and deformed nematics and refutes the common belief that these effects could explain Lehmann’s observations of the rotation of cholesteric droplets subjected to a temperature gradient. It then studies the physics of the dowser texture, which has remarkable properties. This is of particular interest in regards to nematic monopoles, which can easily be generated, set into motion and collided within it. Finally, this book deals with the spontaneous emergence of chirality in nematics made of achiral molecules, and provides a brief historical context of chirality
