Abstract

Abstract Translated from French 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. The invention relates to a liquid crystal matrix made of two plates each consisting of transparent lamellar electrodes, isolated from each other, aligned and contiguous horizontally and vertically, and of a liquid crystalline layer intermediate to the two plates, the transparency and the luminance. each frame element can be modified at will by applying variable voltages to the various lamellar electrodes for the purpose of exploring or obscuring objects placed in the field of view of optical radiation.
