Title: Dynamic Control of Aperture Width Using DDF Phased Array Instrumentation
Abstract: This work presents a technique for controlling the width of a receiving aperture on an ultrasonic phased array system by appropriately programming Dynamic Depth Focusing (DDF) control electronics normally intended for control of depth of focus. The technique simulates deactivation of array elements through use of phase cancellation between neighboring array elements. Underlying principles are discussed. An experimental demonstration is provided.
