Grating — 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… … Wikipedia
Frequency Division Multiple Access — Multiplexverfahren (lat. multiplex „vielfach, vielfältig“) sind Methoden zur Signal und Nachrichtenübertragung, bei denen mehrere Signale zusammengefasst (gebündelt) und simultan über ein Medium (Leitung, Kabel oder Funkstrecke) übertragen werden … Deutsch Wikipedia
Frequency-resolved optical gating — In optics, frequency resolved optical gating (FROG) is a derivative of autocorrelation, but is far superior in its ability to measure ultrafast optical pulse shapes. Further, it can determine the phase of the pulse.In the most common… … Wikipedia
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
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
Spatial frequency — In mathematics, physics, and engineering, spatial frequency is a characteristic of any structure that is periodic across position in space. The spatial frequency is a measure of how often the structure repeats per unit of distance. The SI unit of … Wikipedia
