论文摘要
我们开发了一个简单的坐标转换，可以用微波动力电感探测器（MKID）同型读数方案来补偿该非线性。将该坐标系与规范使用的极性坐标进行比较，并被证明可以改善通常用于估计光子能量的滤波方法的性能。对于坐标非线性主要负责限制其分辨能力的检测器，该技术会导致动态范围增加，我们通过将转换应用于来自HAFNIUM MKID的数据来显示，该数据旨在对具有800至1300 nm范围内波长的光子敏感。新的坐标允许检测器解析波长降至400 nm的光子，从而使该波长的分辨力从6.8提高到17。
We develop a simple coordinate transformation which can be employed to compensate for the nonlinearity introduced by a Microwave Kinetic Inductance Detector's (MKID) homodyne readout scheme. This coordinate system is compared to the canonically used polar coordinates and is shown to improve the performance of the filtering method often used to estimate a photon's energy. For a detector where the coordinate nonlinearity is primarily responsible for limiting its resolving power, this technique leads to increased dynamic range, which we show by applying the transformation to data from a hafnium MKID designed to be sensitive to photons with wavelengths in the 800 to 1300 nm range. The new coordinates allow the detector to resolve photons with wavelengths down to 400 nm, raising the resolving power at that wavelength from 6.8 to 17.
