• Diffraction grating — A very large reflecting diffraction grating. In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions. The directions of these beams …   Wikipedia

• Fiber Bragg grating — A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the… …   Wikipedia

• Echelle grating — An echelle grating (from French, échelle , meaning stairs or ladder) is a type of diffraction grating which is characterised by a relatively low grooves density but is optimized for high diffraction orders. Echelle gratings are, like other types… …   Wikipedia

• Electromagnetically induced grating — (EIG) is a physics phenomenon based on light interference (or, more generally, on electromagnetic fields) where an interference pattern is used to build a dynamic spatial diffraction grating in matter. Introduction Electromagnetically induced… …   Wikipedia

• diffraction grating — Physics. a band of equidistant, parallel lines, usually more than 5000 per inch (2000 per centimeter), ruled on a glass or polished metal surface for diffracting light to produce optical spectra. Also called grating. [1865 70] * * * ▪ optics… …   Universalium

• Ultrasonic 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 …   Wikipedia

• Optical 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 …   Wikipedia
