Photoacoustic effect as a liquid absorbance detector
(Optical Society of America, 1980-09)
A theoretical treatment of the photoacoustic effect for a liquid enclosed in a cylindrical cell is given. Simple analytical expressions for the photoacoustic signal are derived for cw and pulse modulation schemes. Modulation ...
A backscattering formula for acoustic transducers
(A I P Publishing, 1980-06)
A backscattering formula for a single transducer geometry is derived. It expresses the output voltage of the transducer in terms of the angular spectra of scalar and vector acoustic potentials on a plane. The formulation ...
A physical model for acoustic signatures
(A I P Publishing, 1980-01)
A physical model is presented to explain the interference phenomenon that gives rise to the material‐dependent signature obtained from an acoustic reflection microscope. An approximate formula is derived for the peak ...
