论文摘要
我们介绍了MKID系外行动摄像头（MEC），A Z通过J带（800-1400 nm）的积分光谱仪，位于Subaru coronagraphic极端自适应光学光学（SCEXAO）后面的Maunakea上的Subaru望远镜（SCEXAO），在Maunakea上利用了Microhave动力学感应探测器（Mkids）的高度概念（MKIDS）。 MEC是第一个永久部署的近红外MKID仪器，旨在作为IFU运行，并且是带有SCEXAO的多kHz反馈回路中的焦平面波浪传感器。 MKIDS可以实现的无读噪声，快速的时域信息可以直接探测快速斑点波动，这些波动当前限制了地面上最高的对比度成像系统的性能，并将帮助MEC实现其达到$ 10^{ - 7} $的最终目标，即2 $λ/ d $。在这里，我们概述了MEC的仪器详细信息，包括硬件，固件以及减少数据和分析管道。然后，我们讨论MEC当前的天空表现，并以未来的升级和计划结束。
We present the MKID Exoplanet Camera (MEC), a z through J band (800 - 1400 nm) integral field spectrograph located behind The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) at the Subaru Telescope on Maunakea that utilizes Microwave Kinetic Inductance Detectors (MKIDs) as the enabling technology for high contrast imaging. MEC is the first permanently deployed near-infrared MKID instrument and is designed to operate both as an IFU, and as a focal plane wavefront sensor in a multi-kHz feedback loop with SCExAO. The read noise free, fast time domain information attainable by MKIDs allows for the direct probing of fast speckle fluctuations that currently limit the performance of most high contrast imaging systems on the ground and will help MEC achieve its ultimate goal of reaching contrasts of $10^{-7}$ at 2$λ/ D$. Here we outline the instrument details of MEC including the hardware, firmware, and data reduction and analysis pipeline. We then discuss MEC's current on-sky performance and end with future upgrades and plans.
