Focus on the SISDIF project

ANR Grant # JC08_313906

GOAL : Develop new approaches to take advantage of diffuse waves for imaging, monitoring and characterization purposes. Applications include seismology, civil engineering, acoustics...

During the project, we developed the LOCADIFF imaging technique :

Innovation focus price : GRAVIT highlights our invention "LOCADIF : ultrasonic detection and location of centimetric defect appearing in concrete" n°FR 09 50612. .
