SNOM is the acronym for "scanning near-field optical microscopy, "an alternative name for NSOM(near-field scanning optical microscopy). The basic principle of such a kind of technique is quite simple : light passes through a sub-wavelength diameter aperture and illuminates a sample that is placed within its near field, at a distance much less than the wavelength of the light. The resolution achieved is far better than that which conventional optical microscopes can attain.  4, fiche 1, Anglais, - scanning%20near%2Dfield%20optical%20microscopy

Microscopists are now in a position to transfer the refinements of the past 100-year techniques for enhancing contrast and highlighting specific features, such as polarization contrast, immunofluorescence and phase contrast to scanning near-field optical microscopy. With existing scanned-probe microscopes we can "see" the nanometer realm of molecules and microcircuits. As the same technology is applied to optical microscopy, we may eventually come to see that world in the familiar terms of light, shadow and color.  6, fiche 1, Anglais, - scanning%20near%2Dfield%20optical%20microscopy

Ces interactions se produisent à l'échelle moléculaire, c'est pourquoi il est très important d'analyser les propriétés physico-chimiques de la surface à l'échelle atomique et moléculaire. Pour ce faire nous utilisons dans notre groupe les techniques de microscopie à champ proche à balayage : microscopie à effet tunnel (STM), microscopie à force atomique ou effet de force (AFM-SFM), microscopie optique à champ proche à balayage (SNOM).  1, fiche 1, Français, - microscopie%20optique%20%C3%A0%20champ%20proche%20%C3%A0%20balayage

L'équipe [...] a réussi à visualiser ce phénomène biologique en recourant à la microscopie optique à balayage à champ proche (NSOM). Cette technologie d'imagerie éclaire la cellule en canalisant la lumière dans une sonde à fibre optique plus petite qu'un micron. La minuscule ouverture de la sonde (guère plus de 50 nanomètres de diamètre) interdit la diffraction des rayons lumineux qui réduit normalement la résolution en microscopie classique.  3, fiche 1, Français, - microscopie%20optique%20%C3%A0%20champ%20proche%20%C3%A0%20balayage

Given the diversity of today's recording environments, controlling the room's contribution to the sound isn’t always easy. The solution : minimize the room's negative acoustic effects by placing the listener in the speaker's far field and the room's semi-reverberant field. This provides a high ratio of direct-to-reflected sound, while at the same time maintaining sufficient distance to allow the energy of the speaker's woofer and tweeter to combine acoustically. This proven technique is called Direct Field monitoring.  2, fiche 2, Anglais, - semi%2Dreverberant%20field

The carrier landing pattern is similar in some ways to the type of pattern you would use at a land-based field. The major differences lie in the fact that at sea, there are few or no good reference points to judge your position relative to the ship. For example, on your downwind leg, rather than having a nice long parallel section of runway to judge your distance abeam, you only have a fleeting glance at the ship to judge whether you are too close or too far away.  1, fiche 5, Anglais, - distance%20abeam

When AC is applied to a coil, a varying magnetic field will be produced around it. When another coil is placed within that magnetic field, it will induce a current flowing in that coil. This principle is called MUTUAL INDUCTANCE The amount of mutual inductance between the two coils depends on the distance between the two coils, and the angle between the two coils. When two coils are linked together via mutual inductance in this manner, we say that the coils are inductively COUPLED. When the mutually inductive coils are close to each other, we say that they are closely, or tightly coupled. When they are far apart, we say that they are loosely coupled. The greatest amount of coupling occurs when the coils are wound one directly over the other and on a closed iron core. The quantity of coupling between two coils is sometimes referred to as the Coefficient of Coupling.  2, fiche 6, Anglais, - mutual%20inductance
