ABSTRACT:
An ultrasonic transducer arrangement having ultrasonic oscillators, with which electronic delay chains are associated, includes a matrix of column-like ultrasonic oscillators the end faces of which are each connected to control electrodes arranged in the planes of the flat sides of the matrix. On one flat side of the matrix, rows of the oscillators are each provided with a common control line and, on the opposite flat side of the matrix, the jointly controlled groups of ultrasonic oscillators each form a concentric arrangement. This test head can be used selectably as a focusing or as an angle test head and in addition, the focal point can also be displaced in depth.
