High Resolution Infrared Imaging at the 6.5 MMT with Adaptive Optics

摘要设计了一种采用1024 × 1024像素HgCdTe阵列的双通道红外摄像机。该相机最初将用于斯图尔特天文台2.3米望远镜的成像。在第二阶段的工作中，相机将被用于6.5米望远镜，转换的MMT，在那里它将利用望远镜上的自适应光学系统提供一个大视场（~ 40弧秒），校正到JHK波段的衍射限制分辨率。分辨率范围从0.032弧秒FWHM图像在1微米波长（在最好的视力）到常规高Strehl图像0.16弧秒在5微米。2微米以上的波长将使用第二个1024 x 1024的InSb阵列，该阵列将在第三年采购。冷却光学元件包括一个二向色分光器，允许在一次曝光中进行两种颜色的成像。

AST 9623788 ABSTRACT A two-channel infrared camera with a 1024 x 1024 pixel HgCdTe array will be constructed. The camera will initially be used for imaging at the 2.3 meter telescope of the Steward Observatory. In a second phase of the work, the camera will be used at the 6.5 meter telescope, the converted MMT, where it will take advantage of an adaptive optical system on the telescope to provide a large field (~ 40 arcsec) corrected to diffraction-limited resolution in the JHK bands. The resolution ranges from images of 0.032 arcsec FWHM at 1 micrometer wavelength (in the best seeing) to routine high Strehl images of 0.16 arcsec at 5 micrometers. Wavelengths above 2 micrometers will be accessed with a second 1024 x 1024 array of InSb, to be procured in the third year. The cooled optics include a dichroic beamsplitter to allow two color imaging in one exposure.
