Publication number: 20230408452Abstract: An acoustic microscope system is described that includes a container for holding a medium with an object to be measured. Compressional waves are generated by a probe into the medium. The compressional waves travel along an acoustic axis to interact with the object. Shear waves are generated by a shear wave source into the medium. The shear waves travel along a secondary axis which intersects with the acoustic axis at the object with a non-zero angle. The shear waves are configured to cause shear wave oscillations directed transverse to the secondary axis and at least partially directed along the acoustic axis. A measurement of the object is determined based on the compressional waves having interacted with the object as a function of the generation of the shear waves.Type: ApplicationFiled: January 19, 2022Publication date: December 21, 2023Inventors: Paul Louis Maria Joseph VAN NEER, Maurits Sebastiaan VAN DER HEIDEN, Michiel Peter ODERWALD
