This project is to develop and install a 3-5micron imaging system in the 10microns Nulling Infrared Camera now under construction at the University of Arizona for operation at the coherent focus of the Large Binocular Telescope. Having two 8.4-meter mirrors separated by a 14.4-meter baseline on a single steerable platform enables Fizeau (direct imaging) interferometry with 30 milliarcseconds full width at half maximum at 4microns over a field of view limited only by the isoplanatic angle. The Large Binocular Telescope permits unprecedented angular resolution and that combined with the system's high infrared sensitivivity, 20 and 17.5 mag at L-prime and M band respectively, will permit a broad range of astronomical applications and potential groundbreaking science. These include being able to detect warm Jupiters in nearby (d50parsecs) young (t1Gigagyears) systems, investigate local and distant star formation regions, and also study ultra-luminous infrared galaxies at larger redshift.

该项目是在亚利桑那大学正在建造的10微米零化红外照相机上开发和安装一个3- 5微米成像系统，用于在大双目望远镜的相干焦点上工作。在一个可操纵的平台上有两个8.4米的反射镜，它们被一个14.4米的基线分开，使得Fizeau（直接成像）干涉测量法在仅受等晕角限制的视场内具有30毫弧秒的半峰全宽和4微米。大型双筒望远镜具有前所未有的角分辨率，再加上系统的高红外灵敏度，在L-prime和M波段分别为20和17.5等，将允许广泛的天文应用和潜在的突破性科学。 这些包括能够在附近（d50秒差距）的年轻（t1千兆年）系统中探测到温暖的彗星，研究本地和遥远的星星形成区域，以及研究在较大红移的超亮红外星系。
