WebFocusing is the process of timing your piezo-electric elements such that the resulting wavefront adds up in intensity at some points. A specific depth can thus be in focus. … WebDynamic Depth Focussing or DDF is a method of extending a single point of focus to a focal range. DDF is purely artificial and is always calculated on the received (Rx) data. It is important to remember that like point focus, DDF is only possible in the near field.
