Abstract
L'invention concerne une matrice cristalline liquide faite de deux plaques constituées chacune par des électrodes lamellaires transparentes, isolées les unes des autres, alignées et contiguës horizontalement et verticalement, et d'une couche cristalline liquide intermédiaire aux deux plaques, la transparence et la luminance de chaque élément de trame pouvant être modifiée à volonté par application de tensions variables aux diverses électrodes lamellaires aux fins d'exploration ou d'occultation d'objets placés dans le champ de vision d'un rayonnement optique.
