maxima and minima of the scattered laser radiation. The maxima and minima are
the results of intensification and attenuation of coherent wavefront with a random
phase distribution.
A reflective coating is brought onto the surface of skin during the study of biomechanical parameters of skeletal muscles. The coating gives the possibility to estimate
selectively contribution of oscillation movement of muscles to the total of intensity
fluctuation spectrum of the speckle-field form while scattering the laser radiation
from skin and microcirculation of blood in the skin. The scattered dynamic specklefield bears information about the intensity of oscillations of the skeletal muscles, and
thus about the degree of contractility, muscle tone, etc., as well as about the change of
