Abstract
Light absorption in heterogeneous media is investigated by optoacoustic method both theortetically and experimentally. Methods to study light absorption in opaque and turbid media, containing absorbing particles, are discussed. The resolution of the order of 10 microns is realized over the ultrasonic frequency range up to 100 MHz. Optoacoustic method allows one to determine light absorption distribution with the resolution of several microns. These possibilities are demonstrated experimentally for absorbing particles in transparent (water), homogeneously absorbing (cupric chloride solution in water), and turbid (milk) media. The distributions of light absorption in continuously inhomogeneous media (magnetic liquids) are investigated.
