ABSTRACT:
An ultrasonic transducer arrangement having a matrix of oscillators, each such ultrasonic oscillator being formed of a matrix of columnar transducer elements which are electrically controlled together. The spaces between the individual transducer elements are filled with a filler material having an acoustic impedance which substantially differs from the acoustic impedance of the ultrasonic oscillator material from which the transducer elements are formed. The ultrasonic oscillators are provided with electrode strips which are arranged in parallel rows on one flat side of the matrix. The other side of the matrix is provided with electrode strips in the form of parallel columns, so as to be transverse to the direction of the electrode strips on the first side. This arrangement permits high-packing density of the transducer elements, resulting in high resolution which enables line focusing and a close approximation of point focusing.
