Abstract

By analyzing spatial distribution of the laser radiation modulated by ultrasound (the ac photocurrent at ultrasonic frequency) in scattering medium, images of some optical inhomogeneities have been obtained. The signal registration conditions corresponded to the optimal ones to measure the ballistic component of scattered laser light. The changes of the acousto-optic contrast and sharpness were investigated in dependence on the form and size of the absorbing light objects and on the scaftering medium parameters. The image quality of plane and volume buried objects with an equal section in plane orthogonal to the laser radiation axis was similar, quite high, and didn't depend on the object position along this axis.
