Abstract:
A sensing system for examining a subject, said sensing system comprising(a) a transducer device that operates in relation to propagating wavefronts, and (b) said propagating wavefronts propagate in a medium that causes signal attenuation that variably attenuates signals that are distributed over said wavefronts, and (c) attenuation leveling material placed in the path of said propagating wavefronts that compensates for variable attenuation to control signal amplitude for said signals that are distributed over a wavefront, and (d) a fairing device placed in the path of said propagating wavefronts that reduces uneven surfaces of said subject of examination, and (e) a conforming surface placed in the path of said propagating wavefronts that prevents direct contact of a surface of said subject of examination and said attenuation leveling material.
