Abstract
The design principle of the new probe technology is introduced. The calculation of a point cloud defining the transducer shape is discussed in detail. Necessary adaptations are taken into account. The new angle beam probes generate rotationally symmetric sound fields as expected. The DGS accuracy in the working range defined in the EN ISO 16811:2011 is significantly better than the accuracy achieved with traditional angle beam probes.
