抄録

Optical beam deflection method is used for real-time measurements of ultrasonic absorp tionin the frequency range 3 to 40 MHz in liquids. A laser beam is deflected by broad bandultrasonic pulse excited with a 1 MHz-quartz transducer, and the deflection signal is spectral analyzed. The dependence of the spectrum on sound-propagation distance gives absorption coefficients at several harmonic frequencies of the quartz. Absorp tionspectrum is obtained in benzene, o-xylene and carbon disulfide.
