Abstract
An imaging system for non-destructively imaging the cross-section of a workpiece is taught. The image provided portrays the cross-section of the workpiece taken orthogonal to the surface of the workpiece along an operator selected course on the surface. The imaging system comprises: a scanner means for transmitting and receiving acoustical signals and for providing distance increment signals; a transmit and receive control means responsive to each distance increment signal for providing an acoustical drive signal and a column clock signal set. A sampling means is provided that is responsive to the column clock signal set for converting each the echo signal into a corresponding column series of digital values, each value characterizing the amplitude of the echo signal at time corresponding to a respective column clock signal within the echo interval. A storage means is provided for storing each column series of digital values as successive column arrays to form an image array of digital values. The storage means also reads and maps the image array of digital values as display data onto a video monitor.
