Concrete structures like roads and bridges require nondestructive testing methods to identify interior defects without destroying their structure. Most methods send sound waves into the material and ...
Existing defect detection tools using ultrasound rely on phased array ultrasound. In this method, many transducers are pointed in the same direction to generate an image of that specific area. This ...
Researchers created a high-resolution 3D ultrasonic imaging system for concrete that uses broadband ultrasonic signals to automatically adapt to different types of concrete structures. WASHINGTON, Jan ...
