PAUT A-Scan
If 8 elements are fired, the PAUT A-Scan is composed of 8 conventional A-Scans:
- The firing delay for each element is calculated to obtain a beam at the desired angle
- The pulser/receivers are fired in the right sequence
- Each element produces its ultrasound wave. They all interact together to produce a wave front
- The pulser/receivers are placed in listening mode for a period of time corresponding to the range needing to be inspected
- The pulser/receivers transfer the signals to the digitizers
- The signals are synchronized using the same delays as for firing
- The signals are added together to create one A-Scan
- The composite A-Scan is amplified and displayed
