Smith and published by . This book was released on 1963 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of telescopic image abberations at Las Cruces, New Mexico leads to generalizations on the local seeing behavior. Diurnal effects as well as the effects of local winds are included along with the techniques used to study these aberrations. An investigation into the possibilities of image aberration compensation is described. (Author).

This book was released on 1969 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report summarizes the results of a study program with three primary objectives: (1) Development of instrumentation to gather data on atmospheric induced stellar image shimmer, (2) record stellar image shimmer data, and (3) perform required data reduction and analysis to determine the nature and characteristics of stellar image shimmer. The report includes a description of the instrumentation and the results of laboratory and field performance evaluation tests. (Author).
Download or read book The Sun as a Guide to Stellar Physics written by Oddbjørn Engvold and published by Elsevier. This book was released on 2018-11-15 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sun as a Guide to Stellar Physics illustrates the significance of the Sun in understanding stars through an examination of the discoveries and insights gained from solar physics research. Ranging from theories to modeling and from numerical simulations to instrumentation and data processing, the book provides an overview of what we currently understand and how the Sun can be a model for gaining further knowledge about stellar physics. Providing both updates on recent developments in solar physics and applications to stellar physics, this book strengthens the solar–stellar connection and summarizes what we know about the Sun for the stellar, space, and geophysics communities. Applies observations, theoretical understanding, modeling capabilities and physical processes first revealed by the sun to the study of stellar physics Illustrates how studies of Proxima Solaris have led to progress in space science, stellar physics and related fields Uses characteristics of solar phenomena as a guide for understanding the physics of stars
Download or read book Instrumentation for Ground Based Optical Astronomy written by Lloyd B. Robinson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 769 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, the discovery of tools, or evidence that tools have been used, has been taken as proof of human activity; certainly the invention and spread of new tools has been a critical marker of human progress and has increased our ability to observe, measure, and understand the physical world. In astronomy the tools are telescopes and the optical and electronic instruments that support them. The use of the telescope by Galileo marked the beginning of a new and productive way to study and understand the universe in which we live. The effects of this new tool on what we can see, and how we see ourselves, are well known. However, after almost four centuries of developing ever more sensitive and subtle instruments as tools for astronomy, it might have been expected that only a few minor improvements would remain to be made, or that possibly the law of diminishing returns would have taken effect. On the contrary, the new instruments and ideas for new instruments described in this book make it clear that the rate of progress has not diminished, and that this subject is still as exciting and productive as ever. Instrumentation for Ground-Based Optical Astronomy was chosen as the theme for the Ninth Santa Cruz Summer Workshop in Astronomy and Astrophysics.

Download or read book Evaluation and Application of Space Telescope Aberration Sensing Using Phase Diversity written by David J. Lee and published by . This book was released on 1997-03-01 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to mechanical aspects of fabrication, launch, and operational environment, space telescope optics can suffer from unforeseen aberrations, detracting from their intended diffraction-limited performance goals. This dissertation gives the results of simulation and theoretical studies designed to explore how wavefront aberration information for such nearly diffraction-limited telescopes can be estimated via the Gonsalves (least-squares) phase diversity technique. In traditional phase diversity, aberrations are estimated from two images--one conventional, focused image and one image that has been defocused by a known amount. These studies are original and significant in that this effort represents the first time the effects of photon noise have been addressed for this relatively new aberration sensing technique. The effects of image-domain noise such as photon noise are of interest since the aberration estimates are derived from image-domain data. The analysis of this dissertation consists of simulation, theoretical investigation, and experimental application. Simulation studies incorporated models of the proposed Next Generation Space Telescope, as well a more generic, Zernike-aberrated model. Theoretical investigation involved deriving and numerically analyzing the Cramer-Rao lower bound for the phase diversity problem. The practical application dealt with diagnosing aberrations for an adaptive optical, ground-based telescope system.
