AST-0504010 -- Horch/U Mass DartmouthThe award covers the development and construction of the Differential Speckle Survey Instrument. This instrument builds upon a previous speckle imager developed by the investigators that is compatible with any large format CCD and uses the large area of such a CCD as a memory cache of many speckle images prior to a full-frame readout. The Differential Speckle Survey Instrument will use the same idea, but will collect speckle patterns in two colors simultaneously in order to obtain image information below the diffraction limit of a large telescope. The Differential Speckle Survey Instrument will be an important tool for ongoing long baseline interferometer projects.

AST-0504010 -霍希/U质量达特茅斯该奖项涵盖了差分散斑测量仪器的开发和建设。该仪器建立在由研究人员开发的以前的散斑成像仪的基础上，该散斑成像仪与任何大格式CCD兼容，并使用这种CCD的大面积作为全帧读出之前的许多散斑图像的存储器缓存。差分散斑测量仪器将使用相同的想法，但将同时收集两种颜色的散斑图案，以获得低于大型望远镜衍射极限的图像信息。差分散斑巡天仪将是进行中的长基线干涉仪项目的一个重要工具。
