Common methods of ocean remote sensing and seafloor surveying are mainly carried out by airborne and spaceborne hyperspectral imagers. However, the water column hinders the propagation of sunlight to deeper areas, thus limiting the scope of observation. As an emerging technology, underwater hyperspectral imaging (UHI) is an extension of hyperspectral imaging technology in air conditions, and is undergoing rapid development for applications in shallow and deep-sea environments. It is a close-range, high-resolution approach for detecting and mapping the seafloor. In this paper, we focus on the concepts of UHI technology, covering imaging systems and the correction methods of eliminating the water column's influence. The current applications of UHI, such as deep-sea mineral exploration, benthic habitat mapping, and underwater archaeology, are highlighted to show the potential of this technology. This review can provide an introduction and overview for those working in the field and offer a reference for those searching for literature on UHI technology.
海洋遥感和海底测量的常用方法主要由机载和星载高光谱成像仪来进行。然而，水柱阻碍了阳光向更深区域的传播，从而限制了观测范围。作为一项新兴技术，水下高光谱成像（UHI）是高光谱成像技术在大气条件下的延伸，并且正在为在浅海和深海环境中的应用而迅速发展。它是一种用于探测和绘制海底的近程、高分辨率方法。在本文中，我们聚焦于水下高光谱成像技术的概念，涵盖成像系统以及消除水柱影响的校正方法。重点介绍了水下高光谱成像当前的应用，如深海矿产勘探、底栖生境测绘和水下考古，以展示这项技术的潜力。这篇综述可为该领域的从业者提供介绍和概述，并为那些搜索水下高光谱成像技术文献的人提供参考。
