![]() ![]() Only interferometers can achieve this and the Mauna Kea summit is the only place where we can find large optical telescopes spread over such distances,” said Dr. “The next large telescopes will certainly be 30 to 50 meters in diameter, when some of the answers we are looking for would require mile-long diameters. But with an interferometer, the distance between the telescopes, or “baseline,” will determine the angular resolution. With conventional telescopes, the size of a single, primary mirror will determine its ability to resolve small-scale structure on the sky. The results of the first successful test between the two Keck telescopes are described in the January 13th issue of Science.Īn interferometer is a type of instrument that combines light from two or more telescopes to obtain measurements with higher resolution than what could be obtained with a single telescope alone. The ‘OHANA (Optical Hawaiian Array for Nanoradian Astronomy) array, or “interferometer,” will provide ultra-high resolution images of the near-infrared universe, 80 times more accurate than a single 10-meter Keck telescope. Keck Observatory in Hawaii have successfully passed the first test in a project that will link the seven largest telescopes on Mauna Kea together to create a gigantic imaging instrument nearly one half mile (800 meters) in diameter. Mauna Kea (January 13th, 2006) A team of scientists in partnership with the W. The remaining fiber lengths (approximately 200 m for each arm) are wrapped on spools in the basement. Fibers are attached to the telescope structure like regular cables and go through the cable wrap system to prevent any damage when the telescopes rotate in azimuth. Routing of single-mode fibers from the Keck Nasmyth foci down to the basement beam combination laboratory. ![]()
