A method and device for determination of mechanical properties of materials
The present invention using the acoustically induced laser scattering (ALS) avoids these disadvantages by applying the principle of the acousto-optical modulation. By an appropriate arrangement of an ultraultrasonic source, a sonic grid which diffracts laser light is generated in the material. By exclusively using the diffraction peak of
the laser light in a test object, the invention enables new possibilities of non-invasive determination of relevant rheological and other mechanical properties. With this method, a non-destructive measurement of little technical effort and very short measuring times gets possible. Especially
it is, in contrast to conventional rheometers, suitable for in situ measurements. Thus, the invention has a big market potential in the fields of materials science, materials testing and quality assurance.
