Abstract (en)
[origin: WO2007044002A1] A high spatial resolution phase-sensitive technique employs a scanning near field ultrasound holography methodology (47) for imaging elastic as well as viscoelastic variations across a sample surface. Scanning near field ultrasound holography (47) uses a near-field approach to measure time-resolved variations in ultrasonic oscillations at a sample surface (12). As such, it overcomes the spatial resolution limitations of conventional phase-resolved acoustic microscopy (i.e. holography) by eliminating the need for far-field acoustic lenses.
