The Correlation Averaging Module allows you to enhance weak structures in repeated patterns, such as atomic crystals, self assembled molecules, and etched patterns.
When measuring on the nanometer scale the signal-to-noise ratio is often very
small. Traditional filters cannot remove random noise without removing parts of
the real surface structure. However, by the advanced Correlation Averaging technique
it is possible to reduce non-correlated noise and enhance repeated structures
at the same time.
