Among various opticophysical methods [1 - 3] of diagnosing the structure and properties of the optical
anisotropic component of various biological objects a specific trend has been singled out - multidimensional
laser polarimetry of microscopic images of the biological tissues with the following statistic, correlative and
fractal analysis of the coordinate distributions of the azimuths and ellipticity of polarization in approximating
of linear birefringence polycrystalline protein networks [4 – 10]. At the same time, in most cases,
experimental obtaining of tissue sample is a traumatic biopsy operation. In addition, the mechanisms of
transformation of the state of polarization of laser radiation by means of the opticoanisotropic biological
structures are more varied (optical dichroism, circular birefringence). Hereat, real polycrystalline networks
can be formed by different types, both in size and optical properties of biological crystals. Finally, much more
accessible for an experimental investigation are biological fluids such as blood, bile, urine, and others. Thus,
further progress of laser polarimetry can be associated with the development of new methods of analysis and
processing (selection) of polarization- heterogeneous images of biological tissues and fluids, taking into
account a wider set of mechanisms anisotropic mechanisms.
Our research is aimed at developing experimental method of the Fourier polarimetry and a spatialfrequency
selection for distributions of the azimuth and the ellipticity polarization of blood plasma laser
images with a view of diagnosing prostate cancer.
