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 ...

Super-resolution photoacoustic fluctuation imaging with multiple speckle illumination [PDF]
, 2015 In deep tissue photoacoustic imaging, the spatial resolution is inherently limited by acoustic diffraction. Moreover, as the ultrasound attenuation increases with frequency, resolution is often traded-off for penetration depth.
