Lens design for acoustic microscopy
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1988Design criteria for acoustic microscope lenses are examined with respect to their intended application. Aside from buffer rod material and F-number, the factors influencing the lens design are the critical angle for surface wave excitation, lens illumination, and leak rate of the surface wave on the sample.

Scanning tomographic acoustic microscopy
IEEE Transactions on Image Processing, 1995The scanning tomographic acoustic microscope (STAM) was proposed in 1982 as a method of improving the resolution capability of the scanning laser acoustic microscope (SLAM) based on the principles of tomography. By modifying the SLAM with a quadrature detector, tomographic projections that contain both the amplitude and phase information of the ...

Acoustic microscopy of mammalian kidney
Journal of Clinical Ultrasound, 1974AbstractAcoustic micrographs of unstained specimens of mouse kidney were produced at frequencies of 100 MHz and 220 MHz with resolutions of 20μ m and 9μm, respectively. The acoustically revealed structure has been examined in relation to established microanatomy. High contrast details corresponding to connective tissue boundaries of supporting elements

Acoustic microscopy applied to physical acoustics
Review of Scientific Instruments, 1986An acoustic microscope setup has been applied to determine Rayleigh wave velocities in crystals from acoustic materials signatures. The Rayleigh wave velocity close to and above the phase transition in SrTiO3 has been measured as a function of temperature. It has been shown that propane can be used as a coupling liquid between the acoustic lens and the

Scanning acoustic microscopy is a form of microscopy based on the generation and detection of elastic waves in solids. The basic mechanism is the interaction of an acoustic wave with a specimen and the consequent generation of acoustic waves inside the material.
