项目摘要
Bigger is definitely better when it comes to astronomical telescopes. A bigger mirror is important for two reasons: it gathers more light which means that fainter objects can be studied in a reasonable amount of time, and it also provides higher angular resolution so that finer details can be studied. There are quite a number of six to ten meter class telescopes in the world today and astronomers now have their collective eyes on even bigger telescopes called ELTs (Extremely Large Telescopes). There are three collaborations in North America and Europe looking to build telescopes from 24 to 42 meters in diameter (about half the size of a football field).Bigger telescopes are expensive and so are the instruments that go on them to take pictures and analyze the light. These instruments must be bigger to be able to cover the larger high resolution images that are delivered to the telescope focus. A new development is underway at the University of Hawaii Institute for Astronomy in collaboration with Teledyne Scientific and Imaging, LLC that will produce a large detector array for infrared light. At 16 million pixels the new detector will be the largest infrared array ever made and will come at a lower price per pixel. To make cameras that are even bigger, these new detectors will be built so that they can be placed side-by-side to form what is called a mosaic camera. This work is funded by NSF's Division of Astronomical Sciences through its Advanced Technologies and Instrumentation program.
对于天文望远镜来说,越大越好。一个更大的镜子很重要,有两个原因:它可以聚集更多的光,这意味着可以在合理的时间内研究更微弱的物体,它还可以提供更高的角度分辨率,以便研究更精细的细节。今天世界上有相当多的6到10米级的望远镜,天文学家现在集体关注更大的望远镜,称为elt(超大型望远镜)。在北美和欧洲有三个合作项目,希望建造直径24到42米的望远镜(大约是足球场的一半大小)。更大的望远镜是昂贵的,用来拍照和分析光线的仪器也是昂贵的。这些仪器必须更大,以便能够覆盖传输到望远镜焦点的更大的高分辨率图像。夏威夷大学天文研究所与Teledyne科学与成像有限责任公司合作,正在进行一项新的开发,该开发将生产一个大型红外光探测器阵列。1600万像素的新探测器将是迄今为止最大的红外阵列,并且每像素的价格更低。为了制造更大的相机,这些新的探测器将被建造,这样它们就可以并排放置,形成所谓的马赛克相机。这项工作由美国国家科学基金会天文科学部通过其先进技术和仪器项目资助。
