PROCEDE D'OPTIMISATION DE LA FOCALISATION D'ONDES AU TRAVERS D'UN ELEMENT INTRODUCTEUR D'ABERATIONS.

摘要

The method involves emitting waves with phase spatial distribution and amplitude, via a network of sources e.g. piezoelectric transducer (3), and propagating the waves towards a focus zone (6). The distribution and amplitude of the waves emitted by a set of network sources are modified. Disturbance induced by the waves is measured in the zone of interest for the modification of phase distribution and amplitude. Optimal distribution of emission phase and amplitude distribution is deduced from the disturbance measurement to maximize the disturbance induced in the zone. Independent claims are also included for the following: (1) a transmitting system comprising a network of sources (2) a computer program product comprising instructions for executing a method for optimizing focusing of wave (3) a recording medium recording a computer program comprising instructions for executing waves focusing optimizing method.
