Juice - analysis of near-surface defective

摘要

The invention relates to a method and apparatus for ultrasonic testing of test object by means of a testing head, wherein by means of a computer in the case of a juice - analysis for the determination of points in time of the summing amplitudes in the a - image - time signals one of the probe is a function of the sound propagation time of the test head positioned at a measuring point to the location of the voxel is detected and used directly.
