Fig. 5.27 Exterior view of laser specklometer (a) and structural and functional diagram of laser
specklometer (the study of muscle tone) (b): LGN-208 A—He–Ne laser; IRS—the illuminating–
receiving sensor, RID—the radiation input device, PMT—the photomultiplier tube, ND—the
normalization device; ADC—the analog–digital converter; CP—the central processor, ROM—the
read-only memory; CW—the common width, CI—the console interface, CT—the console terminal;
FLF—the filter of low frequencies; SI—the signal intensifier; SCD—the sequential change device.

Tonic state of the muscles under study at rest on the sore and the healthy side as
well as presence and degree of manifestation of the nearest and separate synergies
were compared.
There were developed methods of research and analysis of the studied intensity
fluctuation spectra of dynamic speckle-fields during operation of the laser specklometer both with a spectrum analyzer and with PC of AT286 type. Informative
parameters of spectra were marked out, which reflect some biophysical processes,
in particular alteration of microdynamics of skin and vibrotonic characteristics of
muscles. These parameters became a basis for development of separate software
variants for the laser specklometer.
