论文摘要
未来冷却空间望远镜的远红外探测器需要具有光学噪声等效功率为0.2 AW/\ sqrt Hz的超敏感探测器。在过渡边缘传感器阵列中已经证明了这种性能。一个关键的步骤是展示一种保持性能的制造和组装方法，但可以扩展到适用于在分散光谱仪中应用大规模阵列，以便在较小子阵列中制造阵列可能是有利的。这里的关键是组装和计量学的方法，这些方法可以保持组件空间对齐的必要公差，以维持整体性能。讨论并证明了这些。
Far-infrared detectors for future cooled space telescopes require ultra-sensitive detectors with optical noise equivalent powers of order 0.2 aW/\sqrt Hz. This performance has already been demonstrated in arrays of transition edge sensors. A critical step is demonstrating a method of fabrication and assembly that maintains the performance but that is extendable to create large-scale arrays suitable, for example, for application in dispersive spectrometers where it may be advantageous to fabricate the array from smaller sub-arrays. Critical here are the methods of assembly and metrology that maintain the required tolerances on the spatial alignment of the components in order to maintain overall performance. These are discussed and demonstrated.
