We propose Fourier microscopy based on single-pixel imaging, which uses structured light to computationally illuminate a sample and uses a two-dimensional (2D) pixelated detector to capture the Fourier spectrum image in the back focal plane of the objective. The Fourier spectra collected by different pixels of the detector correspond to light waves diffracted at different angles. Therefore, by regrouping different pixels of the 2D pixelated detector, we built coded single-pixel detectors with different shapes to computationally detect different spectra. Then, we reconstructed multi-mode images using a single-pixel imaging method for dynamic observations. These images have the same field of view, which is more conducive to the comprehensive analysis of samples. Our approach provides a novel development for microscopes and is expected to be widely implemented.

基于单像素成像的傅里叶显微镜用于样品的多模式动态观察

我们提出了基于单像素成像的傅立叶显微技术，该技术使用结构化的光来计算样品，并使用二维（2D）像素化检测器在物镜的后焦平面上捕获傅立叶光谱图像。由检测器的不同像素收集的傅立叶光谱对应于以不同角度衍射的光波。因此，通过对2D像素化检测器的不同像素进行重组，我们构建了具有不同形状的编码单像素检测器，以计算方式检测不同的光谱。然后，我们使用单像素成像方法重建多模式图像以进行动态观察。这些图像具有相同的视野，更有利于样品的综合分析。
