There are still a lot of problems to address before the laser guide star is in regular operation at the largest telescopes to feed adaptive optics in the infrared as well as in the visible, whatever the gain in the variance of the phase error of the wavefronts. In particular in Europe several institutes are working about several of these problems, either from the point of view of theoretical st...
متن کاملObservational Impact of Scattered Light from the Laser Beam of a Laser Guide Star Adaptive Optics System
The scattered light from the sodium laser beam projected from the Keck II telescope during their laser guide star experiment campaign conducted at the end of 2001 was measured using the Subaru Telescope, 221 m away from the Keck II telescope. The purpose of our measurement was to evaluate the observational impact of the scattered light from the laser beam on other telescopes whose field of view...
متن کاملFirst Astronomical Images Sharpened with Adaptive Optics Using a Sodium Laser Guide Star
Adaptive optics with a sodium resonance laser guide star was used at the Multiple Mirror Telescope (MMT) in 1996 April to image the core of the globular cluster M13 (NGC 6205). A 23′′ field was recorded in the Ks-band with image resolution of 0′′.51, when the uncorrected resolution was 0′′.72. Global tilt, not sensed by the laser, was measured from the image motion of a star 35′′ from the cente...
متن کاملModeling Laser Guide Star Aberrations
When using a laser guide star (LGS) adaptive optics system, quasi-static aberrations are observed between the measured wavefronts from the LGS wavefront sensor (WFS) and the natural guide star WFS. We model these LGS aberrations. c © 2007 Optical Society of America OCIS codes: (010.1080) Adaptive optics;(010.7350) Wave-front sensing.
متن کاملRayleigh Laser Guide Star Systems: Application to the University of Illinois Seeing Improvement System
Laser guide stars created by Rayleigh scattering provide a reasonable means to monitor atmospheric wavefront distortions for real-time correction by adaptive optics systems. Because of the l 4 wavelength dependence of Rayleigh scattering, short-wavelength lasers are a logical first choice for astronomical laser guide star systems, and in this paper we describe the results from a sustained exper...
