LARGE OPTICAL SPACE-BASED TELESCOPES
Annotation
An overview of the current state and tendencies in development and construction of high-tech astronomical optical space surveillance systems abroad is provided. Creation of large optical telescopes is reported to be the main trend related to efforts to improve the quality of images by enhancing the basic characteristics of optical telescopes depending on the telescope aperture size. The trend leads to increasing requirements to material and quality of optical elements. Comparative characteristics of optical materials used in the manufacture of mirrors for space-based telescopes are presented. Operating orbital telescopes (HST, Spitzer, Hershel, Gaia) and large optical telescopes under construction (SPICA, JWST, ATLAST) with the composite and flexible mirrors controlled by active systems are considered.
