Abstract
The invention relates to an ultrasonic transducer comprising a plurality of micro-cells, arranged in an array having M rows and N columns, and driving electronic means apt to connect in parallel to each other said micro-cells so as to form at least two sub-groups of said micro-cells, the micro-cells of each sub-group being connected in parallel to each other, at least one column of said array comprising micro-cells belonging to at least two different adjacent sub-groups, so that a radiation emitted in a direction perpendicular to the array columns by said at least one column has a phase that is intermediate between the phases of said at least two different adjacent sub-groups.
