ABSTRACT:
A device for examining objects by ultrasonic echography comprising a focusing network of n ultrasonic transducers and in which the ultrasonic transducers (a,b,c, . . . i, . . . , n-1,n) are made of an electrostrictive material with non-remanent polarization, and the said polarization is effected by a polarization stage comprising: (1) a source (501) of p polarization direct voltages, (2) a demultiplexing and branching circuit (502) receiving, on the one hand, the p polarization voltages and, in the other, combinations of m bits selecting the said voltages in order to supply them to the transducers, (3) a circuit for the determination of a law of sensitivity (503), consisting of a counter (522) whose number of states corresponds at least to the numbers of directions to be explored and of a memory (521), intended to provide the n respective digital combinations corresponding to each state of the counter, and (4) a sequencer (520).
