Instrumentation for Binary Star Speckle Interferometry and Photometry

世界上生产率最高的散斑干涉仪将进行升级，使用改进的计算机系统和新的成像探测器，这将取代现有的但正在恶化的增强型电荷耦合器件探测器。这台散斑干涉仪由Kitt Peak的4米望远镜和Perkin的72英寸望远镜操作，已被用于双星天体测量的长期计划。散斑测光计划是一项重大的新努力，旨在准确确定间隔小至0.035角秒的双星系统中各个组件的颜色和大小。

The world's most productive speckle interferometer will be upgraded using an improved computer system and a new imaging detector, which will replace an existing but deteriorating intensified Charge-Coupled Device detector. This speckle interferometer, operating from Kitt Peak's 4-meter Telescope and Perkin's 72-inch Telescope, has been used in a long-term program of astrometric measurements of binary stars. The speckle photometry program is a major new effort to accurately determine the colors and magnitudes of the individual components of binary systems having separations as small as 0.035 arcseconds.
