Abstract

The invention relates to a method and a device for revealing and distributing magnetic induction lines according to energy thresholds by modification of the trajectory and concentration of electron beams in a cathode ray tube. The device comprises a system (4) for acquisition of the image of a subject (8), a visual display system (5), a source (6) generating a magnetic or electromagnetic field and an imaging system (7). The images obtained are the subject of image acquisition and can be used particularly as patterns for fabric, clothing and/or novelty articles, posters, photographs, advertising media, decoration etc.

Ce document concerne la mise en évidence des répartitions des lignes d'inductions magnétiques (1) à l'aide d'un tube cathodique couleur(2).Suivant les différents seuils d'énergie, on modifie la trajectoire et la concentration des faisceaux d'électrons (3)du tube cathodique
L'ensemble comprend un système d'acquisition(4), de visualisation (5), une source (6) générant un champ magnétique ou électro-magnétique et un système de prise de vue (7). DESCllIPTION
This document concerns the demonstration of the distributions of the magnetic induction lines (1) using a color cathode ray tube (2). Following the different energy thresholds, the trajectory and the concentration of the beams are modified. 'electrons (3) from the cathode ray tube
The assembly includes an acquisition (4), display (5) system, a source (6) generating a magnetic or electro-magnetic field and a shooting system (7).

A l'aide du système d'acquisition, on renvoie l'image d'un suet (8 > sur un écran cathodique couleur (5 > -
On sélectionne une source de magnétisation (6 > que l'on applique sur la face de l'écran cathodique. Cet apport d'énergie va modifier l'image initiale en déviant et concentrant les faisceaux d'électrons (3) du tube cathodique.La nouvelle image, ainsi obtenue, aura des formes et des couleurs qui dépendront de la géométrie de la source de magnétisation, de la direction du champ magnétique par rapport au sens de balayage du tube cathodique, de la position des pâles (nord, s et de la valeur du champ magnétique ou électro-magnétique. Using the acquisition system, the image of a suet (8> is returned on a color cathode screen (5> -
One selects a source of magnetization (6> which one applies to the face of the cathode screen. This contribution of energy will modify the initial image by deflecting and concentrating the beams of electrons (3) of the cathode ray tube. The new image thus obtained will have shapes and colors which will depend on the geometry of the magnetization source, the direction of the magnetic field with respect to the scanning direction of the cathode ray tube, the position of the blades (north, s and the value of the magnetic or electromagnetic field.

La combinaison vectorielle, induction magnétique et faisceaux d'électrons, met en évidence la répartition énergétique et géographique des lignes d'inductions délimitées par les trois couleurs fondamentales, cyan, magenta, jaune su des dérivées en fonction de la couleur sélectionnée.  The vectorial combination, magnetic induction and electron beams, highlights the energy and geographic distribution of the lines of induction delimited by the three fundamental colors, cyan, magenta, yellow or derivatives depending on the selected color.

Les images sélectionnées font l'objet de prises de vues et peuvent être particulièrement utilisées comme motifs pour tissus, articles vestimentaires et/ou fantaisie, posters, photographies, supports publicitaires, décoration etc...  The selected images are the subject of shots and can be particularly used as patterns for fabrics, clothing and / or fantasy articles, posters, photographs, advertising media, decoration etc ...
