Abstract

On the basis of the suggested model of coherent-optical interaction of laser radiation with ultrasonic wave, the influence of geometry of experiment on the amplitude and phase characteristics of ac photo-detector current at the ultrasound frequency was experimentally and theoretically analyzed. For intermediate scattering regime where the ballistic and low-step scattered light components are measurable their contributions to ac photocurrent were separated by experimental data processing. With a use of theoretically predicted and experimentally confirmed optimal conditions of the measurement, the images of the absorbing half-plane were reconstructed in weak scattering media with use of the distributions of the ac amplitude of the current at 3 MHz ultrasound frequency and dc current. The possibilities of the acousto-optical imaging of multiply scattering medium were discussed on the basis of the results obtained after comparison with traditional measurements of dc photocurrent distributions.
