Download or read book Atmospheric Dispersion Corrector for the ILOCATER Spectrography written by Alissa A. Runyon and published by . This book was released on 2016 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: As light enters the Earth’s atmosphere it experiences refraction as it changes medium from vacuum to air. The wavelength dependency of this refraction causes dispersion as different wavelengths of light bend differently. In order to create clear images despite the dispersion effects of the Earth’s atmosphere, new imaging techniques must be developed. iLOCATER is a new diffraction limiting, planet-finding spectrograph being designed and built at the University of Notre Dame for use on the Large Binocular Telescope (LBT) in Arizona. To correct for the dispersion from the atmosphere, an atmospheric dispersion corrector (ADC) using two rotating singlet prisms has been designed and tested. This paper discusses the tests of the ADC and verifies its operation on a test system.

Download or read book Electronic Imaging in Astronomy written by Ian S. McLean and published by Springer Science & Business Media. This book was released on 2008-08-17 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Electronic Imaging in Astronomy: Detectors and Instrumentation describes the remarkable developments that have taken place in astronomical detectors and instrumentation in recent years – from the invention of the charge-coupled device (CCD) in 1970 to the current era of very large telescopes, such as the Keck 10-meter telescopes in Hawaii with their laser guide-star adaptive optics which rival the image quality of the Hubble Space Telescope. Authored by one of the world’s foremost experts on the design and development of electronic imaging systems for astronomy, this book has been written on several levels to appeal to a broad readership. Mathematical expositions are designed to encourage a wider audience, especially among the growing community of amateur astronomers with small telescopes with CCD cameras. The book can be used at the college level for an introductory course on modern astronomical detectors and instruments, and as a supplement for a practical or laboratory class.

Download or read book The Square Kilometre Array An Engineering Perspective written by Peter J. Hall and published by Springer Science & Business Media. This book was released on 2006-01-19 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Square Kilometre Array (SKA) Project is a global project to design and c- struct a revolutionary new radio telescope with of order 1 million square meters of collecting area in the wavelength range from3mto1cm.It will have two - ders of magnitude greater sensitivity than current telescopes and an unprecedented large instantaneous ?eld-of-view. These capabilities will ensure the SKA will play a leading role in solving the major astrophysical and cosmological questions of the day (see the science case at www.skatelescope.org/pages/page astronom.htm). The SKA will complement major ground- and space-based astronomical facilities under construction or planned in other parts of the electromagnetic spectrum (e.g. ALMA, JWST, ELT, XEUS,...). The current schedule for the SKA foresees a decision on the SKA site in 2006, a decisiononthedesignconceptin2009,constructionofthe?rstphase(international path?nder)from2010to2013,andconstructionofthefullarrayfrom2014to2020. The cost is estimated to be about 1000 M . TheSKAProjectcurrentlyinvolves45institutesin17countries,manyofwhich are involved in nationally- or regionally-funded state-of-the-art technical devel- ments being pursued ahead of the 2009 selection of design concept. This Special Issue of Experimental Astronomy provides a snapshot of SKA engineering act- ity around the world, and is based on presentations made at the SKA meeting in Penticton,BC,CanadainJuly2004.Topicscoveredincludeantennaconcepts,so- ware, signal transport and processing, radio frequency interference mitigation, and reports on related technologies in other radio telescopes now under construction.
