Review of Ultrasound Performance From 5 to 20 MHz on an Aluminum Standard

Abstract

An ultrasound system has been set up for nondestructive evaluation of armor tiles and composite systems. Critical system components including an internal pulser-receiver and digitizer board, a stepper motor indexer board, a four-axis scanning frame, an additional two-axis controller, a central processing unit with integrated software package, an immersion tank, and a series of ultrasonic transducers are described in detail. Characteristics and parameters of the various transducers are summarized. Operation of the equipment and utilization of various software tools are detailed to provide a basic method for conducting ultrasound C-scan imaging and analysis. This method is applied to experimental characterization of a standard, which is important for verifying system and transducer parameters as well as exploring system capabilities and limitations. A full system evaluation citing these specific capabilities and limitations is discussed.
