Abstract
The paper presents a new approach to detect impurities, inhomogeneities and anisotropy in condensed matter based on laser generation and holographic observation of nonlinear waves in solids, both transparent and opaque. This approach uses the two phenomena recently discovered by us. First is generation of so-called Poisson waves in a medium surrounding the solid when the strain wave propagates inside it. Second, our studies have proved the physical possibility to generate and observe waves of a new type -- longitudinal strain solitons in nonlinearly elastic waveguides. The soliton detection and recording allows to introduce a new one-pulse technology in nondestructive testing, to determine intrinsic physical properties of nonlinearly elastic materials.
