摘要： 我们提出了一种新型的三维光谱仪设计，可以在一次测量中恢复三维光谱轮廓。 该三维光谱仪设计基于压缩感知的概念，使其能够从屏幕/相机的二维数据中恢复三维信息。 与普通光谱仪不同，三维光谱仪使用宽狭缝而不是窄狭缝，并恢复包含二维空间和一维光谱信息的三维数据立方体。 进行了数值测试以模拟光谱轮廓的恢复。 结果表明，恢复的轮廓与原始轮廓非常吻合。 还表明，从三维光谱仪恢复的信号足够稳健，可以进行进一步的后处理分析。 显示英文摘要

摘要： We present a novel design of 3D spectrometer that can retrieve 3D spectral profile in a single measurement. The 3D spectrometer design is built upon the concept of compressed sensing to make it possible to retrieve 3D information from 2D data from a screen/camera. In contrast to common spectrometers, the 3D spectrometer uses a wide slit instead of a narrow slit and retrieve the 3D datacube that consists of 2D spatial and 1D spectral information. Numerical tests were performed to simulate the retrieval of spectral profiles. The results show that the retrieved profiles match well the original profiles. It is also shown that the retrieved signal from the 3D spectrometer is robust enough for a further post-processing analysis.
