Abstract
A structured illumination microscopic imaging system includes a structured illumination source. A beam shaping lens, an excitation optical filter and a dichroic mirror are provided on the emission light path of the structured illumination source in sequence. An objective lens and a sample are provided on the first optical path of the dichroic mirror in sequence. An emission optical filter, a tube lens, and a detector are provided on the second optical path of the dichroic mirror in sequence. The super-resolution microscopic images with a higher signal-to-noise ratio and higher contrast can be obtained under the premise of lowering the installation and processing precision requirements of the structured illumination microscopic imaging system. Compared to a structured light microscopic imaging system based on digital micromirror arrays or gratings, the system cost is reduced and the system stability is higher.
