Abstract

Erfindungsgemäß werden Schallwellen mit vorgegebener Schallkeule erzeugt, indem mittels eines richtscharfen Ultraschallwandlers (W) Schallwellen mit rotationssymmetrischer Schallkeule erzeugt werden und in der Schallausbreitungsrichtung innerhalb der Fresnel-Zone ein Streukörper (4,7,10,11,17,18) positioniert wird. Hierzu ist eine entsprechende Einrichtung, z.B. gemäß FIG 1 vorgesehen. Die Streukörper sind unterschiedlich ausgeführt, um astigmatische Schallkeulen oder rotationssymmetrische, aufgeweitete Schallkeulen zu erzeugen.
