ABSTRACT

An open source structured illumination microscopy extension for general fluorescence microscope body

Haoran Wang

Leibniz-Institute of Photonic Technology, Jena, Germany

This work demonstrates a structured illumination extension for a general epi-fluorescence microscope.  Its low photon-dose and speed makes structured illumination microscopy (SIM) an ideal super-resolution (up to 2x) fluorescence microscopy for live cell imaging. However, the high price tag of commercial and home build devices makes it a rare and exclusive tool not available to a large group of researchers.

In our setup, a digital mirror device (DMD) is used as a spatial light modulator operating at video frame rates. The setup is fully controlled by the open source software "ImSwitch", and thanks to the SIM reconstruction algorithm, the setup can reconstruct the raw images in real time. The self-contained module adapts to many commercial microscope bodies and can be replicated using off-the-shelf tools and hardware to provide high-resolution microscopy techniques on a small budget.
