9 The diagram of the combination of these two delay laws is represented in figure Figure Steering and focusing delay law Note: The more the beam is steered (relative to the nominal probe angle), the more the risk of occurrence of grating lobes of large amplitude increases. This phenomenon is illustrated in Figure The use of a wedge - for an examination with a refraction angle not equal to zero enables the occurrence of grating lobes that are likely to interfere with the examination to be limited. Note 1 : Main grating lobe Note 2 : Array grating lobeFigure Grating lobes The receiving delay laws applied make it possible to put these elementary signals in phase; which are summed to form the signal received.

10 In most cases, the transmitting and receiving delay laws are identical. Implementation of the examination technique using phased array probes Terms relating to examination technique using phased array probes A shot refers to an acquisition performed with a delay law during transmission. A sequence refers to the set of acquisitions obtained with the same combination of transmitting and receiving channels, for a fixed aperture of the probe. A sequence may be composed of one or severalshots. The salvo refers to the set of acquisitions o
