The elastic deformation of thin mirrors is widely used in systems of adaptive optics, however, of influence of elastic deformations on parameters of reflected polarised light in the literature. Using the method of ellipsometry, the influence of elastic deformation on the residual ellipticity of polished samples made of optical materials was studied. The results obtained during the researches have shown that the appli- cation of elastic deformations leads to essential changes of the minimum ellipticity tgρ of polished samples, which testifies to the necessity to take into account this circumstance for devices of adaptive optics, input windows, cryostats and other optical parts working with the changing temperature.

The sensor of optical image on the basis of non-ideal heterojunctions are investigated in detail. In this work, the opportunity to obtain the image in X-rays was investigated. It is established that investigated sensor is sensitive to soft X-ray radiation. Memory and accumulation of a signal at a room temperature, which is characteristic of the sensor at registration of images in visible light, take place for the images obtained in X-ray range, too, which makes it possible to apply such sensor in medicine and crystallography.

Peculiar properties of carrier photogeneration in the polymer compositions based on polystyrene containing substituted tetrathiafulvalenes – electron donors, 2,4,5,7-tetranitro-9-fluorenone – acceptor of electrons, cationic polymethine dye – tetrafluoroborate 1,3,3-trimethy 1-2-[3-(1,3-dihydro-1,3,3-trimethyl-2I-2-indolyliden)-1-propenyl]-3I-indolium and neutral merocyanine - 5-[6-(1,3-dihydro[1,3,3-trimethyl-2I-indol-2-yliden)-4-phenyl-3,5-(ethylene)-hexa-2,4,6-trien-1-yl] thiobarbituric acid – sensitizers. The photoconductivity in the dye absorption range increases, when the cation dye changed to the neutral, mostly due to mobile carrier with both charges sign photogeneration, and the activation energy of the photoconductivity current decrease. The decrease of photoconduction current activation energy can be related to the organic charged counterion generation in the neutral dye case, and the uncoloured counterion retains more strongly the opposite charge on the photogenerated organic ion in the cation dye case.

In the present work, the use of the cluster analysis method in the “fuzzy logic” concept for the optimization of the cross-selective sensor arrays (“electronic nose”, EN) is considered. This approach enables to purposefully form the sensor arrays with definite chemical functionality optimized for the solution of the specific applied problems. The criteria of the optimization of the sensor response, number and type of the sensor elements are considered with the goal to improve the classification of widely used pharmaceutical products. The optimization of EN array in the kinetic mode and selection of the most informative part of the sensor response enabled to reduce the analysis time, and also the number of sensors in array, to improve the discriminatory capability of the whole array. Being based on the analysis of response kinetic peculiarities, the physical mechanisms determining the peculiarities of adsorption-desorption processes at the interface have been considered.
