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$\lambda / D$. 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.

适用于斯巴鲁 SCExAO 的 MKID 系外行星相机

我们展示了 MKID 系外行星相机 (MEC),az 到 J 波段(800 - 1400 nm)积分场光谱仪,位于 Maunakea 上的斯巴鲁望远镜中的斯巴鲁日冕极端自适应光学(SCExAO)后面,使用微波动感探测器(MKID)作为高对比度成像的使能技术。MEC 是第一个永久部署的近红外 MKID 仪器,设计用作 IFU 和 SCExAO 多 kHz 反馈回路中的焦平面波前传感器。MKID 可读取的无噪声、快速时域信息允许直接探测快速散斑波动,这些波动目前限制了地面上大多数高对比度成像系统的性能,并将帮助 MEC 实现其达到 10 美元对比度的最终目标^{ -7}$ 在 2$\lambda / D$。在这里,我们概述了 MEC 的仪器详细信息,包括硬件、固件以及数据简化和分析管道。然后我们讨论 MEC 当前的空中性能,并以未来的升级和计划结束。
