Taschenbuch. Zustand: Neu. Neuware - Since the invention of the telescope, astronomers have been ableto view fainter and smaller objects in the sky. The mainlimitation to the quality of the images obtained has been, untilrecently, the presence of turbulence in the atmosphere. Tomitigate the effects of the turbulence, adaptive optics systemshave been successfully implemented. Adaptive optics relies uponmeasuring the distortion of the wave-front caused by theatmospheric turbulence, called wave-front sensing, andcompensating for it in an adaptive fashion. The aim of this thesisis to provide a summary of the state-of-the-art of wave-frontsensing and to describe my contributions to the field.The most significant result in the thesis is the derivation of a new wave-front sensing technique.This approach uses the geometric optics approximation, which considers light to travelperpendicular to the wave-front. Consequently, a wave-front slope in a region of the telescopeaperture causes the displacement of a ray of light passing through that region. By taking twodefocused images, it is possible to deduce how the light intensity changed from one image to theother.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Adaptive optics is a powerful new technique used to sharpen telescope images blurred by the Earth's atmosphere. This authoritative book is the first dedicated to the use of adaptive optics in astronomy. Mainly developed for defence applications, the technique of adaptive optics has only recently been introduced in astronomy. Already it has allowed ground-based telescopes to produce images with sharpness rivalling those from the Hubble Space Telescope. The technique is expected to revolutionise the future of ground-based optical astronomy. Written by an international team of experts who have pioneered the development of the field, this timely volume provides both a rigorous introduction to the technique and a comprehensive review of current and future systems. It is set to become the standard reference for graduate students, researchers and optical engineers in astronomy and other areas of science where adaptive optics is finding exciting new applications.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - For many astronomers, Adaptive Optics is something like a dream coming true. Sinee 1609 and the first observations of celestial bodies performed with the help of an optieal teleseope, astronomers have always fighted to improve the 'resolving power' of their instruments. For a long time, engineers have trimmed the optieal quality of the teleseopes, until they finally reaehed the barrier set by the atmospherie turbulence, a few seconds of are. At that point, the intrinsic quality of the site beeame a major issue to establish new observatories with modern telescopes, and astronomers started to desert the urban skies and to migrate toward mountains and deserts. This quest has been sueeessful and a few privileged sites, where the average natural 'seeing' is close to 0. 5', are now hosting clusters of giant telescopes of the 4 m and soon 10 m class. Yet, this atmospherie limit corresponds in the visible wavelength range to the diffraetion limit of a 20 em telescope only. The loss was severe: a faetor 20 in angular and several hundred in peak energy eoncentration, i. e. in deteetivity of resolution very faint objeets. In the beginning of the seventies, two doors half opened to provide a way out of this dead-end. First, the technique of speckle interferometry (and its various related developments) has allowed to restore the diffraetion limit of large telescopes at visible and infrared wavelengths (see, e. g.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Adaptive optics allows the theoretical limit of angular resolution to be achieved from a large telescope, despite the presence of turbulence. Thus an eight meter class telescope, such as one of the four in the Very Large Telescope operated by ESO in Chile, will in future be routinely capable of an angular resolution of almost 0.01 arcsec, compared tot he present resolution of about 0.5 arcsec for conventional imaging in good condition. All the world's major telescopes either have adaptive optics or are in the process of building AO systems. It turns out that a reasonable fraction of the sky can be observed using adaptive optics, with moderately good imaging quality, provided imaging in done in the near IR. To move out of the near IR, with its relatively poor angular resolution, astronomers need a laser guide star. There is a layer of Na atoms at approximately 90 km altitude that can be excited by a laser to produce such a source, or Rayleigh scattering can be employed lower in the atmosphere. But the production and use of laser guide stars is not trivial, and the key issues determining their successful implementation are discussed here, including the physics of the Na atom, the cone effect, tilt determination, sky coverage, and numerous potential astronomical applications.…
