Hyperspectral imaging (HSI) is a promising tool for microscopic histopathology studies. Pushbroom microscopic hyperspectral imaging systems are widely used because of their low cost and easy implementation. However, the spatial resolution of pushbroom HSI systems is limited by the width of the optical entrance slit. A narrower slit leads to longer exposure time and slower imaging speed. In this paper, we explored several spatial resolution enhancement algorithms, originally designed for remote-sensing hyperspectral imaging, for pushbroom microscopic HSI systems. Our results demonstrate that those algorithms could effectively achieve a higher spatial resolution without sacrificing imaging speed.
高光谱成像（HSI）是微观组织病理学研究中一种很有前景的工具。推扫式显微高光谱成像系统因其成本低且易于实现而被广泛使用。然而，推扫式HSI系统的空间分辨率受光学入射狭缝宽度的限制。狭缝越窄，曝光时间越长，成像速度越慢。在本文中，我们探索了几种最初为遥感高光谱成像设计的空间分辨率增强算法，用于推扫式显微HSI系统。我们的结果表明，这些算法可以在不牺牲成像速度的情况下有效地实现更高的空间分辨率。
