ABSTRACT:
It has previously been suggested to indicate, or record images of, internal inhomogeneities in a sample by means of an ultrasonic angle probe which is moved on the surface of the sample, the reflected echo signal being indicated as punctiform position markings in such a way that when added together the markings form an image of the projection of the inhomogeneities on the surface of the sample. It is now suggested that also the amplitudes of the echo signals are indicated, whereby much more information about the inhomogeneities is obtained. The amplitude can be indicated as a variation of the intensity, size and/or duration of the position markings. Another possibility is to indicate the amplitude by the length of a line segment.
