A simple derivation of the field transformation in the optical system for direct and tilted objects is proposed. It is used for developing an algorithm and programs of numerical determination of the spatial resolution of optical systems. It is planned to apply the developed methods to reflection X-ray microscopy.

Optical orientation in transparent nematic liquid crystalline polymer (NLCP) was observed for the first time. In NLCP with dye dopant, the light-induced second-order orientation transition being an analogue of the Freedericksz transition in low-frequency fields is found. The transition threshold is ~10 μW which is lower than the threshold of the light-induced Freedericksz transition in low-molecular nematics by four orders ofmagnitude and is lower than the characteristic value for low-molecular nematics with dye dopant by two orders of magnitude.

The use of non-dual, purely field description of matter in the form of continuously superimposed elementary (radial) densities instead of dual physics of classical fields and point particles makes it possible to overcome nonphysical Newtonian/Coulomb self-energy divergences and to solve the field many-body problem exactly. In this case, the gravitational charge of the radial carrier of energy in common non-empty space is associated with the real part of the integral of complex densities of elementary matter, and the accompanying electric charge is associated with the imaginary part of the same spatial integral. Such unification of classical interactions corresponds to the previously predicted criterion of double unification.

One of the candidates for dark matter particles is the heavy photon. The experiment on the search for these particles using nuclear emulsions irradiated in a positron beam with an energy of 32 GeV is described. Methodical studies for estimating the efficiency of the search for electronpositron pairs and the effective mass determination accuracy are performed.
