微波动力学电感探测器具有很大的潜力，用于大型，非常敏感的探测器阵列，例如，亚毫米成像。由于本质上是在频域中读出，它们特别适合于频域多路复用，允许用一对同轴电缆读出1000个器件。 然而，这将探测器的复杂性从低温转移到温暖的电子设备。我们在这里提出的概念和实验演示的使用快速傅里叶变换光谱仪读出，显示没有恶化的噪声性能相比，低噪声模拟混合，同时允许高复用比。
Microwave kinetic inductance detectors have great potential for large, very sensitive detector arrays for use in, for example, submillimeter imaging. Being intrinsically readout in the frequency domain, they are particularly suited for frequency domain multiplexing allowing ∼1000 s of devices to be readout with one pair of coaxial cables. However, this moves the complexity of the detector from the cryogenics to the warm electronics. We present here the concept and experimental demonstration of the use of fast Fourier transform spectrometer readout, showing no deterioration of the noise performance compared to the low noise analog mixing while allowing high multiplexing ratios.
