The super-resolution fluorescence imaging method can observe the nanoscale structure of different subcellular organelles, and its specificity comes from fluorescence labeling. The label free imaging method avoids the possible impact of staining process on the sample itself, but loses specificity. Therefore, the two have complementary properties, each with its unique advantages and application scope. Integrating two different imaging technologies into the same instrument can broaden its application scenarios. A dual-mode microscopy imaging system was constructed by combining structured light illumination super-resolution microscopy (SIM) and rotational coherent scattering microscopy imaging (ROCS), which can switch between the two modes at will. The system was tested with fluorescent microsphere standard sample and PANC-1 pancreatic cancer cell sample. The spatial resolution of 111 nm and 145 nm were obtained in SIM and ROCS channels respectively, and the imaging speed could reach about 100 Hz. This system has high spatiotemporal resolution fluorescence and label free imaging functions, providing more convenience and possibilities for the research of cell biology.
