AST-0605080/Skrutskie, UVaThe Infrared Astronomy Laboratory at the University of Virginia will continue work on the extension of the sensitivity of Indium Gallium Arsenide arrays into the 2 - 2.32 micron band, continuing to reduce the cost per pixel of ground-based near-infrared astronomical imaging. A test array will be implemented in the Cornell-Massachusetts cross-dispersed low-resolution spectrograph, presently at the 3.5 m Apache Point Observatory. Also, the existing discrete device testing infrastructure in place at the lab will be used to implement a new Indium Gallium Arsenide-based detector design incorporating quantum dots into a single structure that will permit simultaneous imaging at three wavelengths (1, 5, and 10 microns) with bandwidths on the order of 20-30%.

AST-0605080/Skrutskie，UVa 弗吉尼亚大学红外天文实验室将继续致力于将砷化铟镓阵列的灵敏度扩展到 2 - 2.32 微米波段，继续降低地面近红外天文成像的每像素成本。测试阵列将在康奈尔-马萨诸塞州交叉色散低分辨率摄谱仪中实施，目前位于 3.5 m 阿帕奇点天文台。此外，实验室现有的分立器件测试基础设施将用于实施一种新的基于砷化铟镓的探测器设计，将量子点合并到单一结构中，允许在三种波长（1、5和10微米）下同时成像，带宽约为20-30%。
