摘　　要：系统地分析了各种快照式光谱成像技术并进行了对比。依据光谱数据立方体分割到2D空间进行成像的方法,将不同的快照式光谱成像技术分成图像分割、孔径分割、光路分割和频率分割4类,按类别探讨了17种技术方案的原理、优点、缺点与现状,从空间像素数与光谱通道数权衡、图谱匹配、空间采样连续性、光能利用率及动态范围5个方面进行了对比和展望。研究结果有助于相关领域学者快速全面地了解快照式光谱成像仪的研究现状,为进一步提升其综合性能奠定基础。This study systematically analyzed and compared various snapshot imaging techniques.According to the method of spectral data cube segmentation in 2 D space, snapshot spectral imaging techniques are divided into four categories: image segmentation, aperture segmentation, optical path segmentation, and frequency segmentation. The principles, advantages, disadvantages, and current status of 17 technical schemes werestudied for each category.The analysis and comparisonwere based on the following five aspects: the tradeoff between the spectral channels and spatial pixels, matching of space and spectrum, space continuous sampling, light utilization, and detector dynamic range.The results of our study will help researchers in related fields to quickly and comprehensively understand the research status of snapshot spectral imaging, and in addition the results will lay a foundation for further improvement of the overall performance of these techniques.
