Some distance after the slits, the light hit a screen so that the resulting intensity pattern could be observed.

The intensity pattern formed by this scan can be represented by a cosine curve, as seen on the right.

Each electron's wave-function goes through both slits, and hence has two separate split-beams that contribute to the intensity pattern on a screen.

The emission spectrum will typically have a quite different intensity pattern from the absorption spectrum, though, so the two are not equivalent.

Kato fringes are the intensity patterns due to Pendellösung effects at the exit surface of the crystal.

To calculate this intensity pattern, one needs to introduce some more sophisticated methods.

Spatial methods operate in the image domain, matching intensity patterns or features in images.

An image similarity measure quantifies the degree of similarity between intensity patterns in two images.

The diagram at the right shows an intensity pattern roughly corresponding to the spectrum above it.

It has also been shown that intensity patterns will be created at certain fractional Talbot lengths.
