Microscopy Applications and Techniques
Structured Illumination
The technique called structured illumination projects a grid into the focal plane of a widefield fluorescent microscope. The grid is precisely moved in the lateral direction, and several images are acquired at the focal plane, each with the grid in a different position.

Since fluorescence emission from areas in focus varies more significantly per position than emission from out-of-focus areas, it is possible to automatically create an optical section free of out-of-focus blur. Whilst it takes a little more time to acquire the image than with the widefield deconvolution approach, this technique offers greater levels of out-of-focus discrimination.
