我们描述了MIRI焦平面系统的布局和独特的特点。我们从探测器阵列及其读出集成电路（结合放大器单元和多路复用器）、电子设备和控制数据收集和输出信号数字化并传送到JWST航天器电子系统的步骤开始。然后讨论该MIRI数据系统的操作，包括检测器读出模式、子数组操作和数据格式。最后，我们总结了系统的性能，包括数据管道中需要纠正的剩余异常。
We describe the layout and unique features of the focal plane system for MIRI. We begin with the detector array and its readout integrated circuit (combining the amplifier unit cells and the multiplexer), the electronics, and the steps by which the data collection is controlled and the output signals are digitized and delivered to the JWST spacecraft electronics system. We then discuss the operation of this MIRI data system, including detector readout patterns, operation of subarrays, and data formats. Finally, we summarize the performance of the system, including remaining anomalies that need to be corrected in the data pipeline.
