Long Distance Laser Ultrasonic Propagation Imaging System

This study proposes a portable long distance laser ultrasonic propagation imaging (LUPI) system with associated damage visualization algorithms based on anomalous wave propagation imaging (AWPI) methods with adjacent wave subtraction, reference wave subtraction, reference image subtraction, and the variable time window amplitude mapping (VTWAM) for a robust SHM solution.

Ultrasonic Linear Array Medical Imaging System

Modern ultrasound scanners use large either linear or phased array of piezoelectric transducers. Design principle of electronic beamforming networks thus draws heavily from that of adaptive antenna array. However, the interaction of ultrasound with human tissue appears to be much more complicated than that of the electromagnetic wave. While with Xrays we get a shadow image of the system, with u...

Ultrasonic Imaging

The basic principles of ultrasonic B-mode imaging aresummarized. Tissue features that generate contrast andsystem features that control image quality are reviewed inthe context of breast cancer imaging. Approaches to signalmodeling, including B-mode and Doppler techniques, arereviewed to guide methodological design and clinical eval-uation. The article concludes with a b...

Ultrasonic Feature Imaging System for Testing Bimetal Rotor Clad Layer

An ultrasonic feature scan imaging system used for testing delamination flaw probably existing in the bimetal rotor clad layer was studied and developed. The bimetal rotor with nine column holes can be tested automatically. All the wave train of testing result will be saved in computer for post processing. There are various imaging modes including depth imaging and amplitude imaging, to find de...
