11University of Osuna — The University of Osuna (Spanish: Universidad de Osuna), officially the Colegio Universidad de la Purísima Concepción en Osuna ( College University of the Immaculate Conception in Osuna ) was a university in Osuna, Kingdom of Seville, Spain from… …
12Photonics — Refraction of waves of photons (light) by a prism The science of photonics[1] includes the generation, emission, transmission, modulation, signal processing, switching …
13Fiber optic sensor — A fiber optic sensor is a sensor that uses optical fiber either as the sensing element ( intrinsic sensors ), or as a means of relaying signals from a remote sensor to the electronics that process the signals ( extrinsic sensors ). Fibers have… …
14Interferometry — is the technique of using the pattern of interference created by the superposition of two or more waves to diagnose the properties of the aforementioned waves. The instrument used to interfere the waves together is called an interferometer.… …
15Ultrashort pulse — In optics, an ultrashort pulse of light is an electromagnetic pulse whose time duration is on the order of the femtosecond (10 − 15 second). Such pulses have a broadband optical spectrum, and can be created by mode locked oscillators. They are… …
16Distributed temperature sensing — systems (DTS) are optoelectronic devices which measure temperatures by means of optical fibres functioning as linear sensors. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. A high… …
17Frequency-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… …
18Optical add-drop multiplexer — Not to be confused with add drop multiplexer. Optical add drop multiplexer, using a fiber Bragg grating and two circulators. An optical add drop multiplexer (OADM) is a device used in wavelength division multiplexing systems for multiplexing and… …
19Colloidal crystal — A colloidal crystal is an ordered array of colloid particles, analogous to a standard crystal whose repeating subunits are atoms or molecules.[1] A natural example of this phenomenon can be found in the gem opal, where spheres of silica assume a… …
