显微镜在许多研究领域都是必不可少的工具。到目前为止，显微镜在很大程度上仅限于电磁光谱的可见光区域进行成像。在这里，我们提出了一种显微镜系统，它使用单像素成像技术来同时产生可见光和短波红外图像。我们将我们的显微镜应用于各种物体的检查，包括硅CMOS传感器，突出了可见光和短波红外波段的互补性。该系统能够以10至0.6赫兹的相应帧速率产生分辨率在32x32至128x128像素之间的图像。我们引入了一种不需要后处理的压缩技术，导致预测的帧速率从12.5%的压缩比增加到原来的8倍，而相对误差仅为28%。(C)2014年美国光学学会
Microscopy is an essential tool in a huge range of research areas. Until now, microscopy has been largely restricted to imaging in the visible region of the electromagnetic spectrum. Here we present a microscope system that uses single-pixel imaging techniques to produce images simultaneously in the visible and shortwave infrared. We apply our microscope to the inspection of various objects, including a silicon CMOS sensor, highlighting the complementarity of the visible and shortwave infrared wavebands. The system is capable of producing images with resolutions between 32 x 32 and 128 x 128 pixels at corresponding frame rates between 10 and 0.6 Hz. We introduce a compressive technique that does not require postprocessing, resulting in a predicted frame rate increase by a factor 8 from a compressive ratio of 12.5% with only 28% relative error.
