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. WebDynamic depth focusing Dynamic depth focusing (DDF) is a programmable; Phased array probes are made in a variety of shapes and sizes for different applications. Transducer with Dynamic Depth Focusing Good focus Poor focus Conventional focus Dynamic depth focusing: All holes in focus, single pass, single probe FIGURE 3

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. WebDynamic-depth focusing (DDF) takes full advantage of phased-array technology to optimize resolution in depth while minimizing inspection time. To ensure consistent … 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. phormium tenax rainbow sunrise
