Title

Abstract
(EN)
A device for measuring reflected ultrasound and optical signals may include: an optical source; an optical assembly comprising at least one lens, configured to focus reflected optical illumination from a target onto a detector; and an ultrasound transducer aligned to transmit and receive ultrasound radiation co-axially with the reflected optical illumination and wherein the ultrasound transducer at least partially obstructs a path of the reflected optical illumination. An obstruction may be distant from a focal spot of the optical assembly. The device for measuring reflected ultrasound and optical signals may be particularly useful for characterizing fluid behind an ear drum to diagnose otitis media.
(FR)
L'invention concerne un dispositif de mesure d'ultrasons réfléchis et de signaux optiques pouvant comprendre : une source optique ; un ensemble optique comprenant au moins une lentille, configurée pour focaliser un éclairage optique réfléchi à partir d'une cible sur un détecteur ; et un transducteur ultrasonore aligné pour émettre et recevoir un rayonnement ultrasonore co-axialement avec l'éclairage optique réfléchi et le transducteur ultrasonore obstrue au moins partiellement un trajet de l'éclairage optique réfléchi. Une obstruction peut être distante d'un point focal de l'ensemble optique. Le dispositif de mesure d'ultrasons réfléchis et de signaux optiques peut être particulièrement utile pour caractériser un fluide derrière un tympan pour diagnostiquer une otite moyenne.
