Abstract This paper presents a hyperspectral imaging approach using a single-pixel detector. The system consists of a two-stage encoding system based on the concept of Hadamard transform. In contrast with conventional hyperspectral imaging methods where wavelength filters or Fourier spectroscopy is usually adopted, the spectral imaging system in this design uses an encoded slit, a resonant scanning mirror, and a fixed encoder mask to reconstruct the spectral image. The proposed method provides a novel way to set up an easily-controllable single-pixel approach that allows the imager to operate at any wavelength. We present a complete single-pixel hyperspectral imaging system with experimental results to demonstrate its working performance.

使用两级哈达玛编码的单像素高光谱成像仪

摘要 本文提出了一种使用单像素探测器的高光谱成像方法。该系统由基于Hadamard变换概念的两级编码系统组成。与通常采用波长滤波器或傅立叶光谱的传统高光谱成像方法相比，本设计中的光谱成像系统使用编码狭缝、共振扫描镜和固定编码器掩模来重建光谱图像。所提出的方法提供了一种建立易于控制的单像素方法的新方法，该方法允许成像器在任何波长下工作。我们提出了一个完整的单像素高光谱成像系统，并带有实验结果来证明其工作性能。
