Hyperspectral imaging technology is playing an increasingly important role in the fields of food analysis, medicine and biotechnology. To improve the speed of operation and increase the light throughput in a compact equipment structure, a Fourier transform hyperspectral imaging system based on a single-pixel technique is proposed in this study. Compared with current imaging spectrometry approaches, the proposed system has a wider spectral range (400-1100 nm), a better spectral resolution (1 nm) and requires fewer measurement data (a sample rate of 6.25%). The performance of this system was verified by its application to the non-destructive testing of potatoes.
高光谱成像技术在食品分析、医学和生物技术等领域发挥着越来越重要的作用。为了提高操作速度并在紧凑的设备结构中增加光通量，本研究提出了一种基于单像素技术的傅里叶变换高光谱成像系统。与当前的成像光谱方法相比，该系统具有更宽的光谱范围（400-1100nm）、更好的光谱分辨率（1nm）和更少的测量数据（6.25%的采样率）。通过将该系统应用于马铃薯的无损检测，验证了其性能。
