Patent

CA 2656136

The present invention concerns a method for parallel optical decoding of a digital phase image to an intensity image by algorithmic encoding of a data page into phase image and parallel optical decoding by capturing the interference of the phase data page and its copy shifted by one or a few pixels with respect to each other.

La présente invention concerne un procédé de décodage optique parallèle d'une image de phase numérique en une image d'intensité au moyen d'un codage algorithmique d'une page de données en une image de phase et d'un décodage optique parallèle par capture de l'interférence de la page de données de phase et de sa copie, lesquelles sont décalées d'un ou de quelques pixels l'une par rapport à l'autre.
