MetaSpectra+：用于快照高光谱+成像的紧凑宽带超表面相机
MetaSpectra+: A Compact Broadband Metasurface Camera for Snapshot Hyperspectral+ Imaging
用超表面-折射混合组件在单次曝光内同时编码光谱、曝光与偏振，为计算成像中的多路复用采集与后续重建提供了一种紧凑硬件方案；做高光谱重建或快照多模态成像的工作可借鉴其通道独立色散控制的设计思路与重建精度基准。
原文依据 It utilizes a novel metasurface-refractive assembly that splits the incident beam into multiple channels and independently controls each channel's dispersion, exposure, and polarization.

由模型翻译 · 术语统一 · 请对照原文核对关键结论我们提出 MetaSpectra+，一种紧凑的多功能相机，支持两种工作模式：（1）快照 HDR + 高光谱成像，或（2）快照偏振 + 高光谱成像。它采用一种新颖的超表面-折射混合组件，将入射光束分成多个通道，并独立控制每个通道的色散、曝光和偏振。与以往局限于窄波段（10–100 nm）的多功能超表面成像器不同，MetaSpectra+ 的工作范围覆盖几乎整个可见光谱（250 nm）。相对于快照高光谱成像器，它在基准数据集上实现了最短的总光程长度和最高的重建精度。所展示的原型能够从单次快照测量中重建高质量的高光谱数据立方体，以及一幅 HDR 图像或两个正交偏振通道。

We present MetaSpectra+, a compact multifunctional camera that supports two operating modes: (1) snapshot HDR + hyperspectral or (2) snapshot polarization + hyperspectral imaging. It utilizes a novel metasurface-refractive assembly that splits the incident beam into multiple channels and independently controls each channel's dispersion, exposure, and polarization. Unlike prior multifunctional metasurface imagers restricted to narrow (10--100 nm) bands, MetaSpectra+ operates over nearly the entire visible spectrum (250 nm). Relative to snapshot hyperspectral imagers, it achieves the shortest total track length and the highest reconstruction accuracy on benchmark datasets. The demonstrated prototype reconstructs high-quality hyperspectral datacubes and either an HDR image or two orthogonal polarization channels from a snapshot measurement.
