中文摘要：

相比于当前常用的红、绿、蓝三通道成像技术,光谱采集能够提供更多的颜色通道,从而更加精细地反映光源与场景的物理特性,因此可以广泛应用于遥感、材料、医疗、环境等诸多领域.光谱采集技术需要捕获光线在不同时刻和不同空间位置的光谱信息,主要表现在光谱、时间、空间三个维度上的信息获取.传统的光谱采集设备大多采用时序滤波或空间扫描机制记录光谱信息,需要很长的成像时间,因而不能用于光谱视频信息的采集.近年来,伴随着采样理论和电子元器件技术的迅速发展,光谱的视频（动态）采集成为了可能.本文着眼于近年来刚刚起步的光谱视频采集技术,从采集技术的背景和基本原理出发,对于近年来涌现的高分辨率光谱视频采集方法和系统进行介绍,并对于基于直接采集和计算重构的各类技术手段展开讨论,详细阐述这些方法的光学原理、采集理论以及实际系统构建中的问题.此外,本文对各种方法在光谱视频采集中的一些重要性能指标和系统实际运行优缺点进行对比.最后,本文也对光谱视频采集的相关应用与发展前景进行了讨论.

英文摘要：

Speewal capture technique collects information with more color channels than traditional trichromatic sensing. Therefore it provides more detailed properties of the light source and the scene. Possible applications span across lots of fields such as remote sensing, materials science, bio-photonics, environmental monitoring, computer vision and so on. Spectral capture technique needs to record massive data in spatial, temporal and spectral dimension, whereas traditional spectral capture systems suffer from temporal and spatial scanning which is not suitable for video capture. Nowadays, with rapid development in sampling theory and electronic techniques, spectral video acquisition is becoming feasible. This paper presents a review and comparisons on the capturing techniques of high resolution spectral video, especially on hyperspectral video capturing research. In the end, relative applications and future work of hyperspectral video capture are also discussed.
