Presents readers with the basic science, technology, and applications for every type of adaptive lens An adaptive lens is a lens whose shape has been changed to a different focal length by an external stimulus such as pressure, electric field, magnetic field, or temperature. Introduction to Adaptive Lenses is the first book ever to address all of the fundamental operation principles, device characteristics, and potential applications of various types of adaptive lenses. This comprehensive book covers basic material properties, device structures and performance, image processing and zooming, optical communications, and biomedical imaging. Readers will find homework problems and solutions included at the end of each chapter—and based on the described device structures, they will have the knowledge to fabricate adaptive lenses for practical applications or develop new adaptive devices or concepts for advanced investigation. Introduction to Adaptive Lenses includes chapters on: Optical lenses Elastomeric membrane lenses Electro-wetting lenses Dielectrophoretic lenses Mechanical-wetting lenses Liquid crystal lenses This is an important reference for optical engineers, research scientists, graduate students, and undergraduate seniors.

First used in astronomy to correct for blur in ground-based telescopes due to atmospheric turbulence, adaptive optics is now used in vision science to provide diffraction limited imaging of individual retinal cells and to determine the effect of ocular aberrations on the visual acuity and accommodation control. This book provides an introduction to adaptive optics as applied to vision science. The aim is to make the topics tangible for someone completely new to the field, regardless of their discipline. It covers all main concepts including how to develop a basic system from the ground up and also includes information on the current state-of-the-art systems.

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.

Progressive lenses are a type of multifocal lenses that provide a smooth transition from distance to near vision without visible segments or lines. They are designed to correct presbyopia, a condition that affects most people over 40 and causes difficulty focusing on close objects. Progressive lenses have become increasingly popular due to their aesthetic appeal and functional benefits. However, not all progressive lenses are created equal. There are different types of progressive lens designs, each with its own advantages and disadvantages. This book provides a brief overview of the main categories of progressive lens designs, such as conventional, free-form, personalised, digital, and AI-designed progressive lenses. It also explains the key factors that influence the performance and comfort of progressive lenses, such as the fitting parameters, the lens material, the coating, and the frame shape. The book aims to help optometrists, opticians, and eyewear consumers understand the basic principles and features of progressive lens designs and make informed choices when selecting or prescribing them.

This book provides the reader with the broad range of materials that were discussed in a series of short courses presented at Georgia Tech on the design, fabrication, and testing of diffractive optical elements (DOEs). Although there are not long derivations or detailed methods for specific engineering calculations, the reader should be familiar and comfortable with basic computational techniques. This text is not a 'cookbook' for producing DOEs, but it should provide readers with sufficient information to assess whether this technology would benefit their work, and to understand the requirements for using the concepts and techniques presented by the authors.
