Project: Optical Measurement of Guided Acoustic Waves in Solid Media

Acronym: OMeGA
Main Objective:
The coupling of ultrasound waves into solid media on a material surface point followed by the wave detection on another point can be used to infer about the wave propagation conditions. The wave suffers reflections on the material boundaries, but is attenuated or diffracted on existing material discontinuities. It is possible to obtain valuable information about material defects by an accurate analysis of the wave propagation conditions.
In this project we intend to apply the ultrasound method to establish an experimental method of defects detection inside solid structures whose structural health monitoring is of great importance. This is the case of the aircraft structures, the liquid or gas pipelines in nuclear power plants or other containers subject to high pressures. To our knowledge, the most important inspection task at this time is the assessment of possible internal defects inside the stainless steel containers of the International Thermonuclear Experimental Reactor (ITER).
