Represented in this work are theoretical basics for description of fields created
by scattered coherent radiation with using the new correlation parameter – degree of
local depolarization (DLD). The authors have adduced data of measurements of
coordinate distributions for DLD in laser images of healthy and pathologically changed
skin of a rat. Investigated are the values and ranges of changes in statistical (moments of
the first to fourth orders), correlation (correlation area) and fractal (slopes and dispersion
of extremes of logarithmic dependences for power spectra) parameters of coordinate
distributions for DLD. Defined are objective criteria for diagnostics of oncological
changes in the structure of rat skin.
Keywords: laser, polarization, complex degree of coherency, birefringence, correlation,
statistical moments, fractal.
