The … 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.

WebAutomatic Dynamic Depth Focusing (ADDF) is a function currently not available in state of the art phased array NDT instruments. However, it would be a valuable tool to inspect arbitrarily shaped parts or when the part-array geometry is not accurately known. ADDF will avoid the burden of computing and programming focal laws, the complications of CAD … WebA new method with real-time Dynamic Depth Full Focusing (DDFF), in emission and reception, is proposed in this work. It is called Total Focusing Phased Array (TFPA) because it uses concepts of TFM and PA. Omnidirectional emissions are used to create a synthetic aperture as in TFM, while beamforming is carried out along scan lines as in PA ... how to start an illustration business
