论文摘要
高光谱成像（HSI）具有从环境监测到生物技术的广泛应用。当前的快照HSI技术都需要在空间和光谱分辨率之间进行权衡，因此无法同时实现高分辨率。此外，这些技术的资源效率低下，大多数光子通过光谱过滤丢失。在这里，我们使用改良的量子幽灵光谱系统固有的强频谱频谱相关性固有的固有的频谱上的相关性演示了一种快照HSI技术，其中目标是用一个光子直接成像的，并通过一个光子直接成像，并通过伴侣光子从幽灵光谱中获得的光谱信息。由于摄像机边缘附近只有几行像素用于光谱仪，因此几乎没有为光谱牺牲空间分辨率。同样，由于不需要光谱过滤，因此所有光子都会有助于HSI过程，从而使技术更有效。
Hyperspectral imaging (HSI) has a wide range of applications from environmental monitoring to biotechnology. Current snapshot HSI techniques all require a trade-off between spatial and spectral resolution and are thus unable to achieve high resolutions in both simultaneously. Additionally, the techniques are resource inefficient with most of the photons lost through spectral filtering. Here, we demonstrate a snapshot HSI technique utilizing the strong spectro-temporal correlations inherent in entangled photons using a modified quantum ghost spectroscopy system, where the target is directly imaged with one photon and the spectral information gained through ghost spectroscopy from the partner photon. As only a few rows of pixels near the edge of the camera are used for the spectrometer, almost no spatial resolution is sacrificed for spectral. Also since no spectral filtering is required, all photons contribute to the HSI process making the technique much more resource efficient.
