SIM

In the case of “Structured Illumination Microscopy” (SIM), an increase in resolution is achieved by modulating the excitation beam so that the excitation illumination pattern varies with location. When taking a SIM image, the pattern is illuminated from different directions and in different phases with the given and known pattern. We can roughly double the resolution in the x-y direction by using the Fourier analysis on the two-dimensional measured images. With the method approx. 33 fps imaging is available, making it suitable for dynamic scanning. The microscope available at the Nano-Bio-Imaging Core Facility is also suitable for live-cell studies as it is equipped with a CO2 and temperature incubator too.
