Acoustic, psychophysical, and neuroimaging measurements of the effectiveness of active cancellation during auditory functional magnetic resonance imaging [PDF]
, 2009 Functional magnetic resonance imaging (fMRI) is one of the principal neuroimaging techniques for studying human audition, but it generates an intense background sound which hinders listening performance and confounds measures of the auditory response ...

3D reconstruction of a shallow archaeological site from high-resolution acoustic imagery: The Grace Dieu [PDF]
, 2008 Acoustic imaging and characterisation of buried objects (and in particular archaeological materials) in shallow-water (<5 m) is often unsuccessful owing to problems related to vessel-induced bubble turbulence and the restricted acoustic geometry of ...

Performance Evaluation of a Biometric System Based on Acoustic Images
Sensors, 2011 An acoustic electronic scanning array for acquiring images from a person using a biometric application is developed. Based on pulse-echo techniques, multifrequency acoustic images are obtained for a set of positions of a person (front, front with arms ...

Highly-Sensitive and Frequency-Selective Imaging of Defects via Local Defect Resonance [PDF]
, 2014 In this paper, a consistent way to enhance acoustic, optical and thermal defect responses is suggested by using selective ultrasonic activation of defects based on the concept of local defect resonance (LDR).

Exploitation of SAS interferometric phase statistics for coherent change detection
Electronics Letters, 2023 Coherent change detection (CCD) takes advantage of the interferometric processing of synthetic aperture sonar (SAS) images and enables the detection of small scale changes to the scene between image pairs.
