Optoelectronic device for reading of hidden magnetic information from the holograms

The model of the device of reading (visualization) of the hidden magnetic information from the holograms combined with magneto-optical layer is presented in the article. Ways of magnetic images formation on the protected documentation and their reading by magneto-optical methods are proposed. The reading head with the help of magneto-optical meridional Kerr effect allows to observe visually of “effect of blinking” from the hologram with the hidden magnetic layer. During the work the mathematical analysis magneto-optical Kerr or Faraday effects was carried out. The hidden magnetic image based on:

Simulation of heating of biological tissues in the process of ultrahigh-frequency therapy

A physicomathematical model of the temperature distribution over the surface and the bulk of a biological object (human palm) exposed to an ultrahigh-frequency electric field (40.68 MHz) for therapeutic purposes is presented. Various approaches to studying the propagation of laser radiation and radio-frequency electromagnetic waves in biological tissues are considered. The temperature distributions in various biotissues, obtained by numerical solution of the nonstationary heat problem, are presented.__________Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 78, No. 1, pp. 106–111, January–February, 2005.     

Classification measurements: Methods and implementation

This paper considers the conceptual apparatus, basic ideas, structure, and some features of the establishment and development of a new area of research that emerged at the intersection of measurement theory and applied statistics. Examples and methods of solution of problems of classification measurements of random signal distribution shapes and the state of rechargeable batteries based on the use of categorical measurement scales are described.

Some unsolved fundamental problems in this subject are formulated. __________ Translated from Kibernetika i Sistemnyi Analiz, No. 5, pp. 100–110, September–October 2007.     

An evaluation of grazing-incidence optics for neutron imaging

The focusing capabilities of neutron imaging optics based on the Wolter-1 geometry have been successfully demonstrated with a beam of long wavelength neutrons with low angular divergence. A test mirror was fabricated using an electroformed nickel replication process at Marshall Space Flight Center. The neutron current density gain at the focal spot of the mirror is found to be at least 8 for neutron wavelengths in the range from 6 to 20 Å. Possible applications of the optics are briefly discussed.
