7. Advanced applications
Multi-element technology was introduced as a means of deflecting or focusing beams. Numerous methods have been developed to improve control performance, whether by specific activation of elements, application of real-time processing or post-processing. Paradoxically, some of these methods involve unshaped, i.e. unfocused, beams.
7.1 Advanced emission modes
-
Full Matrix Capture (FMC)
This is a generic acquisition mode. It consists of successively activating each element and recording the signals from all the elements on reception: there is therefore no beam formed. For an n-element translator, we obtain n 2 signals containing a large amount of information on the component...
