#### Answer:

The use of fringe patterns in interferometry to determine the relative clarity of an image.

#### Explanation:

To close approximation, the relative shift between fringes of different colors is directly proportional to the amount of lateral displacement of the instrument, with the constant of proportionality equal to the longitudinal chromatic aberration.
