Advanced optics is a technique employed to enhance the performance of optical systems through reduction of the impact of wavefront distortions. Developments in adaptive optics technology and applications have moved ahead at a fast pace. The general idea of wavefront compensation in real-time has been present since the mid-1970s. The first broadly employed application of adaptive optics was for compensating atmospheric turbulence effects in astronomical imaging and laser beam propagation. Whereas some topics have undergone research for years, even decades, new developments and applications in the supporting technologies keep emerging almost every day. This book is a compilation of contributions made by authors from across the world. The topics covered in this book are adaptive optics and the human eye, image post-processing, atmospheric turbulence characterization, deformable mirrors, high power laser distortion compensation, astronomy with huge telescopes, and wave-front sensors among others. Descriptive information on all these topics has been provided in this book.

The objective of this effort was to investigate advances in wavefront sensor technology for use in future adaptive optics systems. The improvements sought over presently developed adaptive optics systems are preliminary in the areas of component efficiency and sub-system complexity, since this would have potential for major operational simplicity and reduced cost. The concept under study in this effort is the Large Scale Integrated Imaging Irradiance (LSI3) sensor. This is based on the Integrated Imaging Irradiance (I3) sensor (U.S. Patent No. 4,141,652). The I3 sensor is based on the Hartmann concepts, but does not suffer from the optical alignment problems inherent to previously developed Hartmann sensors. Another of the major advantages of the LSI3 sensor over the Hartmann sensors (including the previously developed I3 sensor) is that the LSI3 sensor utilizes the full aperture of the system in dividing the input photon flux into the respective quadrants which results in better diffraction - limited resolution. The LSI3 sensor is based on an optical system that is independent of the number of sub-apertures selected. The major tasks of this study included the conceptual design of a small version (approximately 20 channels), a large scale (approximately 200 channels) wavefront sensor, and the evaluation of the expected performance, complexity, and cost of these prototype models. The result of these design advancements is a new wavefront sensor (LSI3) which could provide cost and performance advances for future adaptive optics systems.

This open access book provides a comprehensive overview of the application of the newest laser and microscope/ophthalmoscope technology in the field of high resolution imaging in microscopy and ophthalmology. Starting by describing High-Resolution 3D Light Microscopy with STED and RESOLFT, the book goes on to cover retinal and anterior segment imaging and image-guided treatment and also discusses the development of adaptive optics in vision science and ophthalmology. Using an interdisciplinary approach, the reader will learn about the latest developments and most up to date technology in the field and how these translate to a medical setting. High Resolution Imaging in Microscopy and Ophthalmology – New Frontiers in Biomedical Optics has been written by leading experts in the field and offers insights on engineering, biology, and medicine, thus being a valuable addition for scientists, engineers, and clinicians with technical and medical interest who would like to understand the equipment, the applications and the medical/biological background. Lastly, this book is dedicated to the memory of Dr. Gerhard Zinser, co-founder of Heidelberg Engineering GmbH, a scientist, a husband, a brother, a colleague, and a friend.
