This invention discloses a method of producing, in a solid transparent material (3), a hologram of an object; the method includes the steps of: developing a three-dimensional mathematical model of an electro-magnetic field emanating from the object, the field producing an image of the object; computing a corresponding three-dimensional set of points, light scattered from which reconstructs the field; and focusing a pulsed laser beam into the solid transparent material onto each of the points sequentially, the beam being capable, when focused, of causing optical breakdown in the solid transparent material.

L'invention concerne un procédé permettant de produire un hologramme d'objet dans un matériau solide (3) transparent. Ce procédé consiste à développer un modèle mathématique tridimensionnel d'un champ électromagnétique émanant dudit objet, ce champ produisant une image de l'objet; à calculer un ensemble de points tridimensionnels correspondants, la lumière diffusée à partir dudit ensemble reconstruisant le champ; et à focaliser séquentiellement un faisceau laser pulsé dans le matériau solide transparent sur chaque point, ledit faisceau pouvant, lorsqu'il est focalisé, provoquer une dégradation optique dans le matériau solide transparent.
