Lasers used for weapons guidance will aim at very specific areas of the ship possibly located several meters or tens of meters away from the LWR [laser warning receiver] location. LWRs specifically designed for this application will work outside the main beam where detection is due either to off-axis aerosol scattering or port scattering(due to output optics). Laser radiation is scattered from aerosols(dust particles and water droplets) along the entire beam path, creating a spatially distributed radiation source, which creates an angular distribution of the irradiance at the LWR.  1, fiche 7, Anglais, - aerosol%20scattering

The arrangement of the beam-penetration CRT is similar to that of normal CRT's; the only unusual component is the multilayer phosphor, in which a layer of red phosphor is deposited behind the initial layer of green phosphor. If a fairly low-potential electron beam strikes the tube face, it excites only the red phosphor and therefore produces a red trace. When the accelerating potential is increased, the velocity of the beam striking the phosphor is greater, and as a result the beam penetrates into the green phosphor, increasing the green component of the light output.  1, fiche 12, Anglais, - beam%2Dpenetration%20CRT

Sum Frequency Generation Spectroscopy(SFG) is a technique used to analyze surfaces and interfaces. This spectroscopy method utilizes sum frequency generation, where two light beams mix at a surface and generate an output beam with a frequency equal to the sum of the two input frequencies. From the experiment setup and the output beam, one can deduce the composition, orientation distributions, and some structural information of molecules on a surface. SFG has advantages in its ability to be monolayer surface sensitive, ability to be performed in situ(for example aqueous surfaces and in gases), and not causing much damage to the sample surface.  3, fiche 13, Anglais, - sum%2Dfrequency%20generation

The thermal lens effect was discovered when transient power and beam divergence changes in the output of a helium-neon laser [were observed] after placing "transparent" samples in the laser cavity. It is a photothermal effect and results when energy from a laser beam passing through a sample is absorbed, causing heating of the sample along the beam path. The lens is created through the temperature dependence of the sample refractive index.  1, fiche 14, Anglais, - thermal%20lens%20effect

L'innovation la plus importante de la fin des années 1920 concerne sans nul doute l'introduction des tubes à anode rotative. En 1915, Coolidge avait déjà envisagé de construire un tube à anode tournante, sans pour autant aboutir à un résultat satisfaisant. C'est le physicien Albert Bouwers, chercheur de la firme Philips qui réussit en 1929 à présenter le premier tube à anode rotative, utilisé en téléradiographie. La rotation d'un disque anodique favorise le refroidissement et permet d'appliquer une charge beaucoup plus importante dans un laps de temps plus réduit. Le disque est entraîné par un petit moteur à induction dont la rotation se situe entre 3000 et 9000 tours-minute.  3, fiche 15, Français, - tube%20%C3%A0%20anode%20tournante
