Title (EN) OPTICAL DATA CARRIER SYSTEM
(FR) SYSTEME DE SUPPORT DE DONNEES OPTIQUE
Abstract: front page image
(EN)The present invention provides a method of holographically storing data as in a series of grating structures including m-level coded elements in an optical data carrier, wherein m ≥ 2, the method comprising: forming a grating sampling function as a direct sum of N partial grating sampling functions, each partial grating sampling function having a phase (&phgr; n) and amplitude (dn), wherein each dn has m possible values.
(FR)L'invention se rapporte à un procédé de stockage holographique de données comme dans une série de structures en réseau comprenant des éléments codés de niveau m, dans un support de données optique, m = 2. Le procédé consiste à former une fonction d'échantillonnage en réseau en tant que somme directe de N fonctions d'échantillonnage de réseau partiel, chaque fonction d'échantillonnage de réseau partiel possédant une phase (f n) et une amplitude (dn), chaque dn ayant m valeurs possibles.
