Editing Super-resolution imaging (section)

====Multiplexing spatial-frequency bands====
An image is formed using the normal passband of the optical device. Then some known light structure, for example a set of light fringes that need not even be within the passband, is superimposed on the target.<ref name="Guerra 3555–3557"/><ref name = "Gustaffson"/> The image now contains components resulting from the combination of the target and the superimposed light structure, e.g. [[Moiré pattern|moiré fringes]], and carries information about target detail which simple unstructured illumination does not. The “superresolved” components, however, need disentangling to be revealed. For an example, see structured illumination (figure to left).
