MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202647071083 A) filed by Austral Diagnostics; Ecole Suprieure De Physique Et De Chimie; Universite Paris Cite; and Centre National De La Recherche Scientifique on June 08, 2026, for Acoustic System And Method For Measuring Surface Movements.
Inventors include Couade, Mathieu; and Ing, Ros Kiri.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: The invention relates to a method for detecting movements of a plurality of points (P) on a surface (21), the method comprising a measuring step during which an incident ultrasonic wave is emitted into the air towards the surface, and an ultrasonic wave reflected by the surface (21) into the air is detected. The movements of the surface at a measuring point are determined by calculating a delay and/or phase shift between two path-forming signals for the measuring point. Before the measuring steps, a topography of the surface (21) is determined by means of an optical device. During the measuring steps, the beamforming signals are determined on the basis of the topography of the surface.
