Abstract

Noncontact high-accuracy techniques are very actual in real time in medicine and biology. An analysis of laser light fluctuations may indicate a state of a muscle tissue. In the study spectral characteristics of a dynamic speckle field scattered by skin over a muscle are investigated in detail. Among them: a power of fluctuations, a ratio of spectral amplitudes for two different harmonics, an average frequency of fluctuations, a spectral highwidth, and so on. A variation of these parameters during tonus changing are discussed. The power of fluctuations has the largest dynamic range.
