Abstract

L'invention concerne un imageur rapide pour l'échographie ultrasonore, utilisant un milieu d'interaction acousto-optique pour rendre directement visibles des ondes ultrasonores. Il comprend notamment deux réseaux linéaires de transducteurs 2, 3 dont le premier émet des ondes ultrasonores périodiques vers le corps à examiner 0 et en reçoit des ondes ultrasonores réfléchies qu'il transforme en signaux électriques. Ces signaux sont transmis par l'intermédiaire d'amplificateurs 4 au second réseau linéaire 3 qui les réémet dans une cuve 5 transparente contenant un milieu liquide 6 piézo-optique ainsi qu'un élément d'optique acoustique, tel que miroir et/ou lentille, focalisant les ondes acoustiques. L'image optique de ces ondes est obtenue à l'aide d'un éclairage par un faisceau laminaire mobile et un système de filtrage spatial du type << schlieren >> (striographie). L'invention est utilisable notamment en échographie ultrasonore médicale.
