Abstract
A method and physical and technical design of the laser heterodyne tomography of scattering properties of thick photosensitive materials (media) in the reflection mode are proposed. The method is based on the acoustooptic scanning of a test reflection grating recorded in the medium and on the layer-by-layer collinear heterodyne analysis of the scattered field. The formulas for estimating the spatial resolution capability of the method and the period of test grating are obtained, and the estimate of method’s sensitivity is given in the form of dependence of the heterodyne signal on the depth of grating layer positions. The theoretical conclusions of the work are confirmed experimentally.
