Abstract

La présente invention concerne des dispositifs et méthodes de transport et de contrôle de faisceaux lumineux, notamment pour l’imagerie endo-microscopique dite « sans lentille ». La présente invention s’applique par exemple à l’exploration endoscopique, par exemple d’organes d’un être vivant alors même que celui-ci peut se déplacer librement pendant la mesure. Plus particulièrement, la présente invention permet une mesure « en direct » de la matrice de transmission de la fibre, alors même que la fibre peut subir des changements de conformation. La présente invention concerne également un dispositif de fibre adapté pour la mise en œuvre de la méthode. [Fig. 8]
