Non-destructive testing

Initially developed from nonlinear acoustic technics for micro-damage detection, the DAET technology is adapted for the characterization of solid materials. The existence of microcracks in a homogeneous solid significantly modifies its viscoelasticity behavior which is in connection with the quantity of damage.

Micro-bubble detection

Because of a strong difference of compressibility between the gaseous and liquid phases, the DAET technology has substantial sensitivity to the detection and the quantification of gas microbubbles.
