Abstract
L'invention concerne la réalisation d'hologrammes synthétiques Elle se rapporte à un procédé dans lequel deux groupes de conducteurs 11, 12, disposés transversalement, créent la matière du support M1 des champs électriques locaux qui dépassent une valeur de seuil. Des changements de propriétés de la matière apparaisent ainsi et, après retrait des conducteurs, forment un hologramme. Application à la réalisation d'hologrammes synthétiques en volume.
