Description

In pulse-echo ultrasonic nondestructive testing, a transducer sends an ultrasonic wave into the test sample and receives the reflected wave from discontinuities in the sample. The received energy is converted into an electrical signal by the transducer, resulting in a one-dimensional time domain signal called an A-scan. An alternate method of representing an ultrasonic NDT signal is the C-scan image, which consists of peak values of the A-scan obtained at each position of a raster scan.
