Abstract
In the solids there are many of defects determining their properties. After loading some of the defects are moving, active and some are fixed, passive. The active defects are accompanied through stress waves spreading in the solids. Stress waves called also as acoustic emission or phonon emission can be detected with the very sensitive sensors. Some stress waves can excite in some materials also the light emission called mechanoluminescence what is emission of photons. In the contribution it is shown that both acoustic (phonon) as well photon emission can be used for the measuring and visualization of stress waves.
