Latest Active optics Stories
Raymond Wilson, whose pioneering optics research at ESO made todayâ€™s giant telescopes possible thanks to â€œactive opticsâ€ technology, has been awarded the 2010 Kavli Prize in astrophysics.
Active Optics -- Active optics is a relatively new technology for astronomic telescopes. Most modern telescopes are reflectors, with the primary element being a very large mirror. Historically, a fixed weight-to-diameter relation was used to build these mirrors, limiting their maximum diameter to 5 or 6 meters (200 or 230 inches), like in the Palomar Observatory. A new generation of telescopes uses instead very thin mirrors, uncapable of sustaining themselves. Instead, an array of...
