Grating Definition from Encyclopedia Dictionaries & Glossaries
English Wikipedia - The Free Encyclopedia
A grating] is any regularly spaced collection of essentially identical, parallel, elongated elements. Gratings usually consist of a single set of elongated elements, but can consist of two sets, in which case the second set is usually perpendicular to the first (as illustrated). When the two sets are perpendicular, this is also known as a grid or a mesh.
