Fluorescence microscope refers to any microscope that uses fluorescence to generate an image, whether it is a more simple set up like an epifluorescence microscope or a more complicated design such as a confocal microscope, which uses optical sectioning to get better resolution of the fluorescence. The fluorescence high frequency features are extracted from the variance of the raw images, as in 119 fluctuation microscopy, through a demodulation process using the speckle autocorrelation as a carrier wave, 120 as in structured illumination microscopy.
