The work is aimed at the development and experimental testing of the polarization method for analyzing the polycrystalline structure of the human biological tissues. the main relationships between temporary changes in the statistical structure of topographic maps of the degree of crystallization of histological sections of the internal organs of a person and variations in the magnitude of the statistical moments of the 1st - 4th orders that characterize them are revealed. It is shown that with an increase in the damage duration, the statistical parameters of linear birefringence maps change according to the following scenario — the average and dispersion values decrease, asymmetry and excess, on the contrary, increase
This article researches the proposed physical and mathematical model of a digital coherent optical spectrum analyzer, the spatial spectral bandwidth of which is limited by the diffraction of light on the matrix structure of the modulator. To expand the bandwidth of the spectrum analyzer, proposed to illuminate the modulator with a plane wave that incident on the modulator at a certain angle, similarly to the Leit-Upatnieks hologram. The research of the model has shown that when the modulator is illuminated with an inclined plane wave, the form of the diffraction pattern does not change, but the whole picture is shifted. To expand the operating spectral range (bandwidth), it is necessary that two diffraction maximum of the 0-th and + 1st orders incident into the entrance pupil of a Fourier lens, and when they are recorded, the entire sensitive surface of the matrix radiation detector is fully used. In this case, the operating range of the spectrum analyzer is equal to twice the Nyquist frequency of the modulator.
There are a number of problems in the manufacture of precision instruments related to the accuracy of the size of details, which affects the quality of the product. Therefore, it is necessary to take into account those distortions of the geometry of the element of details, which are machining, for example, on CNC machines. At work the main possible variants of deviation from geometric sizes, which lead to loss of accuracy of the detail are considered

The method of increasing the realism of forming graphic scenes due to adaptive editing is proposed. The user is given the opportunity to change the image of a three-dimensional object using the functions of perturbation. At the same time, a higher degree of smoothness of the form is achieved compared to the use of splines. The use of excitation functions makes it possible to achieve an acceptable level of detail, which allows you to manage the realism of the formation of graphic scenes.
