The invention relates to a WORM type (write-once-read-many) three-dimensional optical memory made by fluorescent photosensitive materials. The optical memory is based on one-photon and two-photon processes for writing and reading the digital information. Since for reading the fluorescence is used a high reading sensibility is obtained. The invention has the advantage of a novel device for storage and retrieval of the information having application in computers.
L'invention concerne une mémoire optique tridimensionnelle de type WORM (inscriptible une seule fois) élaborée à partir de matériaux fluorescents photosensibles. Cette mémoire optique est basée sur des processus à un photon et à deux photons permettant d'écrire et de lire l'information numérique. Etant donné qu'on utilise la fluorescence pour la lecture, on obtient une sensibilité élevée de lecture. L'avantage présenté par l'invention consiste en un nouveau dispositif servant à mémoriser et à extraire l'information pouvant être mise en application dans des ordinateurs.
