论文摘要
我们在本文中描述了用于探测总元件动感探测器（Lekid）的在线算法。 Lekids是天文学的毫米波长检测器。 Lekid阵列目前在西班牙IRAM望远镜的IRAM望远镜，Tenerife的Teide天文台望远镜和智利的Apex 12米望远镜的Concerto中进行操作：Nika2。 Lekids是能够在毫米波长下检测传入的光的微波谐振器，并且非常适合频率多路复用（目前在单个微波指南中最多可达360个像素）。然而，它们用于天文观测需要特定的读数和采集系统来处理仪器和多重复杂性，并适应观察性要求（例如，快速采样率，背景变化，在线校准，光度计算准确性等）。本文介绍了从识别每个Lekid的共振频率到对背景变化引起的lekid共振频率的连续自动控制的不同治疗步骤。
We describe the on-line algorithms developed to probe Lumped Element Kinetic Inductance Detectors (LEKID) in this paper. LEKIDs are millimeter wavelength detectors for astronomy. LEKID arrays are currently operated in different instruments as: NIKA2 at the IRAM telescope in Spain, KISS at the Teide Observatory telescope in Tenerife, and CONCERTO at the APEX 12-meter telescope in Chile. LEKIDs are superconducting microwave resonators able to detect the incoming light at millimeter wavelengths and they are well adapted for frequency multiplexing (currently up to 360 pixels on a single microwave guide). Nevertheless, their use for astronomical observations requires specific readout and acquisition systems both to deal with the instrumental and multiplexing complexity, and to adapt to the observational requirements (e.g. fast sampling rate, background variations, on-line calibration, photometric accuracy, etc). This paper presents the different steps of treatment from identifying the resonance frequency of each LEKID to the continuous automatic control of drifting LEKID resonance frequencies induced by background variations.
