Space debris is a growing problem for satellites in Earth orbit. With the ever increasing number of launches this problem is likely to get worse. While large pieces of debris can be tracked from the ground small pieces of less than 1 cm are difficult and are the more numerous. MSSL is part of the newly funded Global Network on Sustainability In Space (GNOSIS) which brings academic and industrial groups together to address the issues in space debris. A detector system comprising single photon sensitive detectors with spectral resolution and able to take a full picture every few microseconds offers a potential way of identify very small pieces of debris. Such a system does not currently exist. This research project aims to identify the drivers, the system specification, how such a system could be built and possible proof of concept demonstration. Such a system will be investigated not only for ground based use at telescopes but also as a space based imaging system.

对于地球轨道上的卫星来说，空间碎片是一个日益严重的问题。随着发射次数的不断增加，这个问题可能会变得更糟。虽然可以从地面追踪大块碎片，但小于 1 厘米的小碎片却很困难，而且数量较多。 MSSL 是新资助的全球太空可持续发展网络 (GNOSIS) 的一部分，该网络将学术和工业团体聚集在一起，共同解决太空碎片问题。探测器系统由具有光谱分辨率的单光子敏感探测器组成，能够每隔几微秒拍摄一张完整图片，提供了一种识别非常小碎片的潜在方法。目前尚不存在这样的系统。该研究项目旨在确定驱动程序、系统规范、如何构建这样的系统以及可能的概念验证演示。这样的系统不仅将被研究用于望远镜的地面使用，而且还将作为天基成像系统进行研究。
