Abstract

Un procédé de transmission de données représentatives d’un hologramme numérique (H) représenté par un ensemble d’atomes (ak) ayant chacun un spectre de diffraction (Sk) dans un plan d’observation (PO) comprend les étapes suivantes : - détermination d’un ordre pour des ensembles (ak) comprenant chacun au moins un atome (ak), en fonction d’une distance, dans le plan d’observation (PO), entre une position d’observation (O) et une position (Ck) associée à l’ensemble concerné (ak) ; - transmission, pour une partie au moins desdits ensembles (ak) et dans l’ordre déterminé, de données descriptives dudit au moins un atome (ak) compris dans l’ensemble concerné (ak). Un dispositif de transmission associé est également décrit. Figure pour l’abrégé : Figure 1
