Zone Plate Signals
Zone plate video test patterns, or simply “zone plates”, have become important
tools for the evaluation of modern video processing systems and techniques.
They are called zone plates because the classical circular pattern looks like an
optical zone plate (which uses the principles of Fresnel diffraction to focus and
intensify light). Today, however, the name has been applied to a wide variety of
stationary and “moving” test patterns.
