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.

Download or read book Polychromatic Adaptive Optics to Evaluate the Impact of Manipulated Optics on Vision written by María Viñas Peña and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The eye is an optical instrument that projects scenes of the visual world onto the retina. However the human eye is far from being a perfect optical system, and, as a consequence, the images projected on the retina are blurred by ocular aberrations, as well as diffraction and scattering. Therefore in the last years, multiple technologies based on wavefront sensing and Adaptive Optics (AO) have been developed for the measurement and correction of ocular aberrations. As a result important knowledge has been gained on the contribution of the different components of the eye to the degradation of image quality. However the processes underlying neural adaptation to ocular aberrations are not yet well understood. Understanding the effects of a particular low order aberration, astigmatism, is particularly attractive to investigate adaptive processes in the visual system due to the inherent oriented nature of the blur that it produces. Typically, the impact of ocular aberrations on vision is studied using wavefront sensors with monochromatic, generally infrared, light. However, the retinal image quality is degraded by the presence of both monochromatic and polychromatic aberrations in the ocular optics. The study of the impact of retinal image quality on vision should therefore consider both the aberrations in the visible light, as well as the effect of chromatic aberrations. In addition optical and structural properties of the eye change with age and with certain ocular conditions and treatments, altering the natural aberrations, as well as the interactions between monochromatic and chromatic aberrations, and consequently the visual function. xvi Summary of the thesis The understanding of the interactions of these aberrations and their effect upon correction is essential to explore the limits of human spatial vision, and to design and optimize new alternatives of correction of Presbyopia/Myopia and more complex individualized refractive corrections. In this thesis we have used AO techniques to study the effect of specific monochromatic aberrations and their combinations on vision, to test neural adaptation to those aberrations and their correction, to measure chromatic aberrations of the eye in normal and pseudophakic eyes, and to test vision with simulated multifocal solutions for Presbyopia...

Book excerpt: The 4th International Workshop on Adaptive Optics for Industry and Me- cine took place in Munster, ̈ Germany, from October 19 to October 24, 2003. The series of International Workshops on Adaptive Optics for Industry and Medicine beganwiththe?rstworkshopinShatura/Russiain1997,thesecond workshop took place in Durham/England in 1999, and the third workshop was held in Albuquerque/USA in 2001. The workshop series started out as a true grassroots movement and kept an informal spirit throughout all four workshops. Many personal friendships and scienti?c collaborations have been formed at these meetings. This fourth workshop was supposed to be held in Beijing, China. H- ever, the program committee decided in May 2003 to move the workshop to Munster ̈ due the general perception that the SARS (Severe Acute R- piratory Syndrome) cases reported in China could lead to a large epidemic. Despite this rather short notice the workshop in Munster ̈ was attended by about 70 people. Incidentally, the workshop coincided with the 50th anniv- sary of adaptive optics, because it was October 1953 when Horace Babcock published his famous paper “The possibilities of compensating astronomical seeing” in the Publications of the Astronomical Society of the Paci?c.
