WebOct 1, 1994 · The Total Focusing Method (TFM) yields a focused image in emission and in reception while Phased Array (PA) imaging provides Dynamic Depth Focusing (DDF) in reception only. Besides, most NDE applications have two propagation media, where refraction at the interface complicates time-of-flight (TOF) and focal law computations.
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.
