Introduction to MF-SIM
In the field of fluorescence biological imaging, general interest is more and more turned towards video-rate 3D super-resolution microscopy. SIM is a good candidate for fast acquisition but until now, the acquisition of focal stacks was always performed sequentially. In this project, we aim to combine the fast-SIM set-up with a multi-focus detection scheme  and thus build a so-called “multi-focus structured illumination microscope” (MF-SIM).
Sketch of the MF-SIM set-up
The excitation arm is a clone of the fast-SIM system existing in the group [5, 6], with one major difference: this set-up is going to be a 3-beam SIM. The detection arm follows a multi-focus detection scheme, the important components being the multi-focus grating (MFG) which produces the desired multi-focus effect, the chromatic correction grating (CCG) and the multi-faceted prism which together correct for chromatic dispersion in the emitted fluorescence light .
