Scanning acoustic Doppler microscopy and scanning acoustic correlation microscopy
Ultrasonics, 2002Acoustic microscopy with vector contrast at 100 MHz in a fluid with immersed particles is used to detect the flow profile in front of a microscopic orifice. The velocity profile concerning the component in axial direction of the focused beam is derived from the phase contrast.

Acoustic Force Elastography Microscopy
IEEE Transactions on Biomedical Engineering, 2023Hydrogel scaffolds have attracted attention to develop cellular therapy and tissue engineering platforms for regenerative medicine applications. Among factors, local mechanical properties of scaffolds drive the functionalities of cell niche. Dynamic mechanical analysis (DMA), the standard method to characterize mechanical properties of hydrogels ...

Acoustic Microscopy by Atomic Force Microscopy
Applied Physics Letters, 1994We have constructed an atomic force microscope enabling one to image the topography of a sample, and to monitor simultaneously ultrasonic surface vibrations in the MHz range. For detection of the distribution of the ultrasonic vibration amplitude, a part of the position-sensing light beam reflected from the cantilever is directed to an external knife ...

The acoustic microscope is a new entry in the field of microscopic imaging. It comes after a delay of many years, but now appears to be well established. At last year's conference of the Royal Microscopical Society in London, for example, the booth traditionally reserved for new instruments was used to introduce commercial versions of acoustic ...

This paper describes tunneling acoustic microscopy (TAM), which is based upon a scanning tunneling microscopy (STM) and a technique for detecting an acoustic wave. The principle of TAM is to detect fine strains generated in the STM sample. It enhances the features of STM without reducing its ability, and enables us to image nonconducting materials.

Abstract The principle of the scanning acoustic microscope is becoming increasingly well known (Lemons and Quate, 1979; Briggs, 1985). For any wave motion, the wave-length is equal to the wave speed divided by the frequency. Thus by increasing the frequency sufficiently the wavelength can be made as small as you like.
