The role of contacts in the direct measurement of the noise temperature of samples heated with a current May 13th, 2012

admin

The effect of the type of contacts between the wire sample and the current input leads on the excess current noise is investigated.
The spectral characteristics of this noise and the current dependence of their spectral densities are determined. It is established
that only a welded contact ensures that there is no excess noise voltage in the 20–200

An original working standard of the unit of magnetic induction gradient May 13th, 2012

admin

An original operating standard of the unit of magnetic induction gradient, developed at the Mendeleev Institute of Metrology,
is described which enables one to calibrate working standards, intended, in turn, for calibrating industrial magnetic gradiometers.
The total expanded uncertainty (k = 2) of the reproduction of the unit is 0.3% in the 0.01–10 mT/m range.

An uncooled high-performance antenna-type microbolometer receiver May 13th, 2012

admin

The results of the development of an integrated high-performance antenna-type microbolometer and a computer experiment to
investigate its expected parameters and characteristics are presented. It is shown that the use of a metamaterial in the heat-sensitive
element, which is the load of a double-threaded spiral antenna, enables the main parameters of the receiver, which determine
its practical suitability, to be improved.

Use of data on color discrimination thresholds for measurement of color differences May 13th, 2012

admin

A new method for the measurement of color differences is described. By means of the method, it becomes possible to find the
shortest (i.e., in terms of color discrimination thresholds) path between two color points which in a standard non-equicontrast
CIE 1931 color space is not a straight line. The method is based on local transformations of infinitely small regions of a
given color space with the use of data on color discrimination thresholds obtained by interpolation or approximation of experimental
data.

Calibrated Fresnel stepwise attenuator of laser radiation power May 13th, 2012

admin

A calibrated polarization-independent Fresnel attenuator of laser radiation power based on two Dove prisms is proposed and
implemented. A method of alignment of such an attenuator relative to the axis of the laser beam and a method of determining
the principal directions of polarization of the laser radiation is proposed. By means of model calculations it is shown and
experimentally confirmed that imperfections in the manufacture of the prisms and assembly of the attenuator may be compensated
by rotating the structure by given angles accompanied by corresponding variations in the total reflection factor of the system.
