微波动力学电感探测器（MKID）是超导探测器，能够计数单个光子并测量其在UV、光学和近IR中的能量。MKID具有微波频率下的固有频域复用（FDM），允许构建和读出大阵列。由于微波FDM，MKID不需要用于类似检测器的复杂低温多路复用电子器件，例如过渡边缘传感器，而是将这种复杂性转移到室温电子器件，在室温电子器件中，它们提出了强大的信号处理挑战。在本文中，我们描述了第一次成功的努力，建立一个读出的光子计数光学/近红外天文仪器，阵列相机的光学近红外分光光度计。该读数基于天文信号处理和电子研究合作组织开发的开源硬件。主要为射电望远镜后端设计，它足够灵活，可用于各种信号处理应用。
Microwave kinetic inductance detectors (MKIDs) are superconducting detectors capable of counting single photons and measuring their energy in the UV, optical, and near-IR. MKIDs feature intrinsic frequency domain multiplexing (FDM) at microwave frequencies, allowing the construction and readout of large arrays. Due to the microwave FDM, MKIDs do not require the complex cryogenic multiplexing electronics used for similar detectors, such as transition edge sensors, but instead transfer this complexity to room temperature electronics where they present a formidable signal processing challenge. In this paper, we describe the first successful effort to build a readout for a photon counting optical/near-IR astronomical instrument, the ARray Camera for Optical to Near-infrared Spectrophotometry. This readout is based on open source hardware developed by the Collaboration for Astronomy Signal Processing and Electronics Research. Designed principally for radio telescope backends, it is flexible enough to be used for a variety of signal processing applications.
