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.

Acoustic transducer for acoustic microscopy
The Journal of the Acoustical Society of America, 1991A shear acoustic transducer-lens system in which a shear polarized piezoelectric material excites shear polarized waves at one end of a buffer rod having a lens at the other end which excites longitudinal waves in a coupling medium by mode conversion at selected locations on the lens.

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

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 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.

No doubt, light microscopy still plays the leading role in the qualitative and quantitative microscopical examination of metals. The introduction of quantitative techniques like manual and automated image analysis, microscope photometric reflectance measurements, analysis of elliptically polarized light by polarizing microscopy, interference microscopy
