Starfire laser beam. Astronomer with the 1.5-metre telescope at the Starfire Optical Range (SOR) as it projects a copper vapour laser beam (green). This laser creates an artificial 'star' in the upper atmosphere,within the field of view of the SOR's main 3.5-metre telescope. The latter detects any change in shape of the artificial 'star' due to air turbulence,and uses a flexible adaptive optics mirror to compensate. This effectively counters the familiar 'twinkling' of stars,and offers highly-improved resolution over conventional ground-based observatories. The SOR was developed by a team led by Robert Fugate and was built in New Mexico,USA | |
