An investigation of lucky imaging techniques
We present an empirical analysis of the effectiveness of frame selection (also known as Lucky Imaging) techniques for high resolution imaging. A high-speed image recording system has been used to observe a number of bright stars. The observations were made over a wide range of values of D/r0 and exposure time. The improvement in Strehl ratio of the stellar images due to aligning frames and sele...
متن کاملAstraLux: the Calar Alto Lucky Imaging Camera
AstraLux is the Lucky Imaging camera for the Calar Alto 2.2-m telescope, based on an electron-multiplying high speed CCD. By selecting only the best 1-10% of several thousand short exposure frames, AstraLux provides nearly diffraction limited imaging capabilities in the SDSS i’ and z’ filters over a field of view of 24×24 arcseconds. By choosing commercially available components wherever possib...
متن کاملI-55: Molecular Imaging Overview
Molecular imaging is the noninvasive visualization of normal as well as abnormal cellular processes at a molecular or genetic level of function. It is used to provide characterization and measurement of biological processes in living animals and humans (in vivo). The discipline of molecular imaging evolved rapidly over the past decade through the integration of cell biology, molecular biology a...
متن کاملLucky imaging and aperture synthesis with low-redundancy apertures.
Lucky imaging, used with some success in astronomical and even horizontal-path imaging, relies on fleeting conditions of the atmosphere that allow momentary improvements in image quality, at least in portions of an image. Aperture synthesis allows a larger aperture and, thus, a higher-resolution imaging system to be synthesized through the superposition of image spatial-frequency components gat...
متن کاملAn Efficient Lucky Imaging System for Astronomical Image Restoration
The resolution of astronomical imaging from large optical telescopes is usually limited by the blurring effects of refractive index fluctuations in the Earth’s atmosphere. In this paper, we develop a lucky imaging system to restore astronomical images through atmosphere turbulence on 1.23m telescope. Our system takes very short exposures, on the order of the atmospheric coherence time. The rapi...
