Abstract

Lateral resonance low-frequency vibrations responsible for the temporal changes of the skin surface relief arise at the muscular contraction. On exposure of the skin area over the contractional muscle to coherent radiation, the change of the speckle field intensity fluctuations occurs. The dynamics of this process is dictated by the dynamics of the object under study. So, making investigations on the spectral properties of the reflected scattered laser radiation, we can judge about the character of changing the skin surface itself.
