  • Acoustic-optical imaging methods and systems
    Patent number: 11957435
    Abstract: An acousto-optic imaging method in which light waves and unfocused acoustic waves having various directions of propagation m are emitted in a medium, by spatially modulating the amplitude of the ultrasonic transducers of an array of transducers according to several periodic spatial amplitude modulations j, and the resulting optical signal Smj(t) is captured. For each direction of propagation m, the signals Smj(t) are spatially demodulated in order to determine a signal Sm(t) used to reconstruct the image of the medium.
    Type: Grant
    Filed: March 11, 2019
    Date of Patent: April 16, 2024
    Assignees: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, ECOLE SUPÉRIEURE DE PHYSIQUE ET DE CHIMIE INDUSTRIELLES DE LA VILLE DE PARIS, SORBONNE UNIVERSITE, UNIV PARIS XIII PARIS-NORD VILLETANEUSE
    Inventors: François Ramaz, Jean-Luc Gennisson, Jean-Baptiste Laudereau, Clément Dupuy, Jean-Michel Tualle
