A method of detecting an object located within a dynamic scattering media, the method comprising: i) directing a continuous coherent light wave of predetermined wavelength into the media; ii) detecting dynamically scattered light emerging from the media; iii) correlating the detected light photons in the time or frequency domain; iv) determining the presence of an object from analysis of differences between said correlation and the correlation which would arise from photons scattered by the media only; and v) determining the approximate position of the object within the media from said analysis of the correlation and knowledge of the mean transport path of the light wave of predetermined wavelength within the media.

L'invention concerne un procédé permettant de détecter un objet placé dans un milieu de diffusion dynamique. Ce procédé consiste à (i) diriger une onde de lumière cohérente présentant une longueur d'onde prédéterminée dans le milieu; (ii) détecter de manière dynamique la lumière diffusée émergeant du milieu; (iii) corréler les photons de lumière détectés dans le domaine de fréquences ou temporel; (iv) déterminer la présence d'un objet à partir de l'analyse des différences entre ladite corrélation et la corrélation qui se produirait à partir de photons diffusés par le milieu uniquement; et (v) déterminer la position approximative de l'objet dans le milieu, à partir de ladite analyse de la corrélation et de la connaissance de la trajectoire de transport moyenne de l'onde de lumière d'une longueur d'onde prédéterminée dans le milieu.
