Abstract

La présente invention concerne un instrument médical comportant un premier étage optique, un séparateur spectral, un capteur d'image, et un processeur de diagnostic. Le premier étage optique prend en compte la surface tissulaire d'un patient. Le séparateur spectral, attaqué par le premier étage optique, reçoit des commandes en entrée. Le capteur d'image est optiquement alimenté par le séparateur spectral. Il donne en sortie une image numérisée. Le processeur de diagnostic comporte, d'une part une interface d'acquisition d'image, alimentée en entrée par le capteur d'image, et d'autre part une interface de commande de filtre, donnant en sortie des commandes revenant à l'entrée de commandes du séparateur spectral.
