Optical cross section — or OCS is a value which describes the maximum amount of optical flux reflected back to the source. The standard unit of measurement is . It is dependent on the geometry and the reflectivity at a particular wavelength of an object. Optical cross… … Wikipedia
Optical heterodyne detection — is an important special case of heterodyne detection. In heterodyne detection, a signal of interest at some frequency is non linearly mixed with a reference local oscillator (LO) that is set at a close by frequency. The desired outcome is the… … Wikipedia
Flux method — is a method of crystal growth where the components of the desired substance are dissolved in a solvent (flux) and growth takes place at relatively low temperatures. The method is particularly suitable for crystals needing to be free from thermal… … Wikipedia
Optical power — For the power of light, see Radiant flux and Luminous flux. Optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or… … Wikipedia
Flux optique — Le flux optique perçu par un observateur en rotation (dans ce cas, une mouche). Les flèches représentent la direction et la vitesse du mouvement[1]. Le flux optique est le mouvement apparent des objets, surfaces et contours d une scène visuelle,… … Wikipédia en Français
Flux qubit — In quantum computing, flux qubits (also known as persistent current qubits) are micrometer sized loops of superconducting metal interrupted by a number of Josephson junctions. The junction parameters are engineered during fabrication so that a… … Wikipedia
Optical fiber connector — An optical fiber connector terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so that light can pass. Better connectors lose… … Wikipedia
Optical lattice — Simulation of an optical lattice potential. An optical lattice is formed by the interference of counter propagating laser beams, creating a spatially periodic polarization pattern. The resulting periodic potential may trap neutral atoms via the… … Wikipedia
Rapid single flux quantum — In electronics, rapid single flux quantum (RSFQ) is a digital electronics technology that relies on quantum effects in superconducting materials to switch signals, instead of transistors. However, it is not a quantum computing technology in the… … Wikipedia
