Diffraction grating - Wikipedia
网页In optics, a diffraction grating is an optical grating with a periodic structure that diffracts light, or another type of electromagnetic radiation, into several beams traveling in different directions (i.e., different diffraction angles).
Grating - Wikipedia
网页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). [1]

衍射光栅 - 维基百科，自由的百科全书
网页衍射光栅 （diffraction grating）是 光栅 的一种。 它通过有规律的结构，使入射 光 的 振幅 或 相位 （或两者同时）受到周期性空间 调制。 衍射光栅在光学上的最重要应用是作为 分光 器件，常被用于 单色仪 和 光谱仪 上。 实际应用的衍射光栅通常是在表面上有沟槽或刻痕的平板。 这样的光栅可以是透射光栅或反射光栅。 可以调制入射光的相位而不是振幅的衍射光栅现在也能生产。 衍射光栅的原理是 苏格兰 数学家 詹姆斯·格雷戈里 发现的，发现时间大 …

网页Manufactured by assembling a series of equally spaced metal bars to connecting cross members, bar grating is available in three popular materials; mild carbon steel, 6000 series aluminum and 300 series stainless steels. Additionally, Interstate Gratings can produce gratings constructed with other specialty metal alloys.
4.5: Diffraction Gratings - Physics LibreTexts
网页2022年9月12日 · Diffraction gratings are key components of monochromators used, for example, in optical imaging of particular wavelengths from biological or medical samples. A diffraction grating can be chosen to specifically analyze a wavelength emitted by molecules in diseased cells in a biopsy sample or to help excite strategic molecules in …
1. Introduction to Diffraction Gratings - SHIMADZU CORPORATION
网页A diffraction grating is an optical element that divides (disperses) light composed of lots of different wavelengths (e.g., white light) into light components by wavelength. The simplest type of grating is one with a large number of evenly spaced parallel slits.
网页More generally, a periodic transparency’s complex amplitude transmission may be expressed as a Fourier series expansion: amplitudes. plane waves (diffraction. orders), propagation angle. diffraction efficiencies.
