Dynamic depth focusing
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. … WebFocusing may be at a specific plane, such as (True) Depth, Projection (vertical plane) or some other Focal Plane focus. The other opti on is to focus at a fixed sound path. In all cases, the ability to focus is a function of th e near zone of the beam and can only occur for sound paths less than the near field of the unfocused aperture.
