光栅 Grating

(重定向自Gratings)

光栅是一种非常重要的光学组件。

广义的光栅定义为:可以使入射光的振幅或相位(或两者同时)受到周期性空间调制的光学组件。只能使光受到振幅调制或相位调制的光栅,分别称为振幅光栅和相位光栅。按工作方式分,光栅又可分为透射光栅(透射光受调制)和反射光栅(反射光受调制)。

光栅每单位长度内的刻痕多少,主要决定于所分光的波长范围(两刻痕距离应与该波长数量级相近),单位长度内的刻痕多,色散度越大。光栅的分辨本领决定于刻痕多少。利用全息摄影技术制备的光栅称“全息光栅”,不像机刻光栅刻痕有周期性误差。

通常所说的光栅,是指利用衍射效应对光进行调制的衍射光栅。但也存在利用其它原理对光进行调制的光栅,如晶体折射率光栅。

Graphs of sine, square, triangle, and sawtooth gratings. The Y axis shows luminance; the X axis shows space or distance.

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.
