ABSTRACT:
Process for producing complex ultrasonic transducers comprising cutting out a piezoelectric ceramic block along lines which are parallel to one another by means of at least two rows of channels making it possible to produce elementary transducers and selecting the cut elements so as to obtain the desired complex transducer shape, wherein the selected elements are electrically interconnected by one of their faces by means of a conductive deposit and the other face of said elements is raised to reference potential.
Application to the production of ring grating or annular transducers.
