Acoustic microscope based on magneto-elastic wave phase conjugator

Andrey Brysev, Leonid Krutyansky, Philippe Pernod, Vladimir Preobrazhensky

Acoustic C-scan imaging (acoustic microscopy) by means of supercritical parametric wave phase conjugation (WPC) is studied experimentally. A phase conjugator based on a magneto-acoustic active material is used for compensating phase distortions introduced by solid and polymer aberration layers...

Elaboration and characterization of PNZT thin films deposited on silicon by RF cathodic sputtering

T. Haccart, Eric Cattan, Denis Remiens

Pb(Zr,Ti)O3 (PZT) and Pb(Zr,Ti,Nb)O3 (PNZT) thin films have been grown on platinized silicon substrates by RF magnetron sputtering followed by a post-annealing treatment. The niobium, Nb, concentration varied from 1 to 7 at.% by increment of 1 at.% The effects of the Nb introduction on the PZT...

Microwave radiometric imaging (MWI) for the characterisation of breast tumours

Stéphane Mouty, Bertrand Bocquet, Roger Ringot, N. Rocourt, Patrick Devos

We have developed a new prototype of microwave radiometric imaging devoted to the measurement of the temperature inside a dissipative media. The main application we are looking for, is the non-invasive thermometry of human tissues. We obtain quite satisfactory results in the early characterisation...
