A '''grating''' is any regularly spaced collection of essentially identical, [[Parallel (geometry)|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).<ref>"[http://www.supshitl.com/] {{Webarchive|url=https://web.archive.org/web/20140702173530/http://www.supshitl.com/|date=2014-07-02}}" by sanorient, [[The frp Demonstrations Project]].</ref> When the two sets are perpendicular, this is also known as a [[wikt:grid|grid]] (as in [[grid paper]]) or a [[mesh]].
