Optimize synthetic aperture focusing: advanced signal analysis techniques assist ultrasonic testing to maximize the information collected.

From: Quality | Date: August 1, 2006| Author: | Copyright information

Ultrasonic testing of materials can be done in several ways using different types of instruments, ranging from thickness gages for localized measurements to multi-axis automated C-Scan scanners for imaging of complex parts. While these instruments can satisfy the needs of most applications, some situations require advanced signal analysis techniques in order to maximize the information collected from the tested structure.

One of the problems related to structure inspection is the correct identification of the ultrasonic echoes and time-of-flight related to defects. ...
