Super-resolution microscopy allows the observation of sub-cellular structures with a resolution beyond diffraction limit of conventional fluorescence microscopy. However, most super-resolution microscopes have a limited imaging depth due to the inhomogeneous refractive index of the sample that leads to optical aberrations. Adaptive optics has been successfully adopted by many imaging techniques, including 3D Structured illumination microscopy (SIM). We use a fast deformable mirror to modulate the wavefront of fluorescence to compensate for optical aberration and changing focus position at the same time. Adaptive optics successfully extends the depth, the range and the speed of 3D-SIM imaging.
