Abstract

Abstract Translated from French L'appareil comporte une source piézoélectrique, répartie sur une surface d'oscillations élastiques brèves comportant des crêtes négatives et des moyens de focaliser les oscillations sur la cible. La fréquence des oscillations est réglée entre 0,3 et 10 MHz et la durée des trains d'ondes, à des valeurs comprises entre 1 µs et 1 ms. La cadence des tirs est comprise entre quelques Hz et 2 ou 3 KHz. The apparatus comprises a piezoelectric source, distributed over a surface of brief elastic oscillations comprising negative peaks and means for focusing the oscillations on the target. The frequency of the oscillations is adjusted between 0.3 and 10 MHz and the duration of the wave trains, at values between 1 µs and 1 ms. The rate of fire is between a few Hz and 2 or 3 KHz.
