我们提出了一个通过多模光纤使用单像素成像显微镜的概念证明。我们提出了两种实现方式，一种使用振镜扫描仪和扩散板，一种使用数字微镜器件（DMD）。使用这些设置，我们可以在50微米芯光纤的远端产生数千个不同的散斑图案，作为用于单像素成像的照明图案。我们表明，散斑图案之间的相关性可以低至30%和重复性高达98%的3200图案的样本，并显示使用远端检测器的示例单像素图像。
We present a proof of concept for microscopy through a multimode fiber using single pixel imaging. We present two implementations, one using galvo scanners and a diffuser plate and one using a digital micromirror device (DMD). Using these setups we can generate thousands of distinct speckle patterns at the distal end of a 50 micron core fiber as illumination patterns for single pixel imaging. We show that the correlation between speckle patterns can be made as low as 30% and the repeatability as high as 98% for a sample of 3200 patterns, and show example single pixel images using a distal detector.
