The Acoustics and Ultrasound Lab (AUL) was established in 2010 by external research funds from the National Science Foundation (NSF) and the Office of Naval Research (ONR). The Lab currently supports several research activities, specifically those sponsored by the NSF Partnership for Innovation (PFI) program in the area of acoustics and ultrasound technologies. The main objective of the AUL, directed by Dr. Sridhar Santhanam, is to conduct experimentations and obtain measurements that would aid in proof of concept in ultrasound imaging, image analysis, and acoustic signal processing. Data collected at the AUL allows validation of newly devised as well as existing ultrasound imaging algorithms and acoustic signature detection and classification. In essence, the AUL focuses on developing and utilizing emerging signal processing techniques to address key problems in biomedical ultrasound, nondestructive evaluation, and structural health monitoring. It promotes acoustic and ultrasound education on the cross-disciplinary use of acoustic technologies in electrical, mechanical and civil engineering practices. In particular, the AUL facilities support the multidisciplinary Acoustic Technologies for Industrial Testing course offered for freshmen engineering students.
The AUL is currently undertaking research projects in ultrasound Time-Reversal processing for improved imaging and detection, multiple-input multiple output (MIMO) sensor array beamforming, ultrasound multipath exploitation, ultrasound image analysis, and structural health monitoring.
