Anotácia knihy

This monograph describes the "Lucky" imaging method developed at the University of Cambridge between 1999 and 2003. This technique allows the distorting effects of the Earth's atmosphere to be reduced, so that high resolution images of astronomical sources can be captured. The Lucky Exposures method is passive, relying on a high frame-rate camera in the image plane of a telescope to record the atmospheric speckle patterns. In the past the poor signal-to-noise performance of high frame-rate cameras has often limited passive high-resolution observations to relatively bright targets. Through a combination of novel processing techniques and new L3Vision camera technology, the Lucky Exposures method can now image much fainter targets. Details of these processing techniques and an assessment of the L3Vision performance are presented in this monograph. From good astronomical observatories, up to one quarter of the night sky is within range of a suitable reference star for this technique. The processing techniques described are applicable to data taken with a wide range of astronomical instruments, including observations using webcams on small- to medium-sized telescopes.
