标题： MetaH2: A Snapshot Metasurface HDR Hyperspectral Camera

摘要： 我们提出了一种超表面相机，该相机能够在快照中联合执行高动态范围（HDR）和高光谱成像。该系统通过在图像传感器上同时形成具有独特功率比和色差的多个空间复用投影，将曝光 bracketing 和计算断层扫描成像光谱仪（CTIS）集成在一起。随后，通过深度重建模型处理测量数据，生成HDR图像和高光谱数据立方体。我们的仿真研究显示，所提出的系统在基准数据集上的重建精度高于之前的快照高光谱成像方法。我们组装了一个工作原型，并在真实场景中展示了从600纳米到700纳米波长范围内60分贝动态范围和10纳米光谱分辨率的快照重建。 显示英文摘要

摘要： We present a metasurface camera that jointly performs high-dynamic range (HDR) and hyperspectral imaging in a snapshot. The system integrates exposure bracketing and computed tomography imaging spectrometry (CTIS) by simultaneously forming multiple spatially multiplexed projections with unique power ratios and chromatic aberrations on a photosensor. The measurements are subsequently processed through a deep reconstruction model to generate an HDR image and a hyperspectral datacube. Our simulation studies show that the proposed system achieves higher reconstruction accuracy than previous snapshot hyperspectral imaging methods on benchmark datasets. We assemble a working prototype and demonstrate snapshot reconstruction of 60 dB dynamic range and 10 nm spectral resolution from 600 nm to 700 nm on real-world scenes from a monochrome photosensor.
