Abstract

L'invention concerne un procédé permettant de produire un hologramme généré par ordinateur (CGH) à l'aide de l'algorithme propre à la diffraction. Ce procédé permet de produire une surface d'onde courbée à partir d'un seul hogel, au lieu de produire les ondes planes obtenues dans l'état de la technique. Le procédé susmentionné permet à la surface d'onde provenant d'un seul hogel de produire un point dans le volume de l'image. Une surface d'onde imaginaire est émise depuis chaque point dans le volume de l'image et elle est échantillonnée à une pluralité de points sur toute l'étendue du hogel. Ces échantillons sont utilisés pour produire un ensemble de coefficients de Fourier complexes pouvant être utilisés pour s'approcher de la forme d'onde d'origine.
