Abstract
The theoretical analyze of coherent acousto-optical interaction in the turbid medium resulting in the appearance of ultrasound modulation of the photo-detector current has been fulfilled. Analysis of the influence of tissue scattering properties and geometry of experiment on spatial resolution of technique of acousto-optical imaging by using of considered model is made. The relations between amplitude and phase of the ac current and the receiver system parameters are derived. The optimal conditions for measurements of the ac current on ultrasound frequency are determined. The experimental testing of these conditions have been accomplished with focused ultrasound wave at 3 MHz. The noise characteristics of detection system were studied as well.
