Grating
81Ultrasonic grating — An ultrasonic wave is a sound wave having a frequency greater than 20 kHz. Because of the very small wavelength of ultrasonic waves compared to X rays they have considerable penetrating power. The human ear can not recognize ultrasonic waves, but …
82Holographic grating — A holographic grating is a type of diffraction grating formed by an interference fringe field of two laser beams whose standing wave pattern is exposed to a polished substrate coated with photoresist. Processing of the exposed medium results in a …
83Optical axis grating — Optical axis gratings (OAGs) are gratings of optical axis of a birefringent material. In OAGs, the birefringence of the material is constant, while the direction of optical axis is periodically modulated in a fixed direction. In this way they are …
84Diffraction grating — Diffraction Dif*frac tion, n. [Cf. F. diffraction.] (Opt.) The deflection and decomposition of light in passing by the edges of opaque bodies or through narrow slits, causing the appearance of parallel bands or fringes of prismatic colors, as by… …
85diffraction grating — A variety of filter composed of lined grooves in a thin layer of aluminum copper alloy on a glass surface; used in spectrophotometers to disperse light into a spectrum. See monochromator. * * * diffraction grating n …
