Differential Speckle Survey Instrument

AST-0504010--霍奇/U质量达特茅斯奖包括差分式散斑测量仪器的开发和建造。该仪器建立在研究人员之前开发的散斑成像器的基础上，该散斑成像器与任何大幅面CCD兼容，并在全帧读出之前使用这种CCD的大面积作为许多散斑图像的存储器缓存。差分散斑测量仪将使用相同的想法，但将同时收集两种颜色的散斑图案，以便获得大型望远镜衍射极限以下的图像信息。差分散斑测量仪将是正在进行的长基线干涉仪项目的重要工具。

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.
