Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The main purpose of this overview is to make an effort at joining the widely
spread practical tendency of “damping the noise” with the non-apparent but presumably
perspective thesis “using the noise” through the realization of “information properties of
noise”. The paper deals with physical peculiarities of the equilibrium thermal radiation,
which have been considered within the black body model for the case of ultimate
restrained photon flows inside an ideal (“lossless”) optical communication channel.
Restrictions connected with the uncertainty relations have been used to determine critical
interrelations between the thermal radiation parameters and the sizes of the thermal
radiator and the ideal photodetector. The conception of the “intrinsic micro-amounts of
chaos” has been proposed, and its usefulness was discussed. Principle feasibility has been
considered for a distant identification of a small-sized thermal radiator by means of
detecting its thermal radiation. A single small-size radiator has been phenomenologically
treated within the black body model. It has been shown that it is possible to obtain a
quantitative evaluation of the temperature and the size of a small-size radiator through
measurement of the thermal radiation fluctuations in case when the optical image of the
radiator is unavailable.
