The method of the direct comparison of the laser interferometers and method processing of the interferometry measurement results by the least square method (LSM) is present. The additive part of the measurement error for each pair of the interferometers is evaluated and the multiplicative part of the measurement error for each interferometer is evaluated too by LSM. Uncertainty by A tape by LSM is evaluated for all parameters. Results of the comparison of the three interferometers are presented.

The accuracy of the measurement of the main photometric characteristic of the emitter determines the error for determining the total light flux of the light sources, especially light emitting diodes, for which it should not exceed 5 per cent. Existing measurement methods with the use of integrated spheres, goniophotometers and goniophotometers of the near field require a great deal of time and have a great deal of value. To eliminate these shortcomings, a method for measuring the characteristics of light sources with directed light distribution is proposed based on the use of a set of meters located in a plane perpendicular to the main direction of the source radiation propagation. On the basis of this method, a photometer for measuring the characteristics of the directional light sources is developed, which allows to quickly, in real time, determine the characteristics of the emitters. The method of determining the parameters of light distribution of directed sources of light for the construction of its photometric body is not required to use a rotary means. Taking into account the significant influence of temperature fluctuations on the characteristics of LED light sources, it is possible will upgrade the proposed method for determining the photometric body of the radiation source in real time and when the temperature changes due to the introduction of additional elements in the future.

The purpose of this study is to perform a comparative analysis of the experimentally obtained and calculated values of the measuring windings total EMF amplitudes of the eddy current transducer with spatially periodic fields when magnetic and nonmagnetic cylindrical product are placed in it. To realize this goal in the work, a transducer with translational symmetry of excitation magnetic field has been developed. Translation symmetry typical example is the field of a long current conductor. The paper considers quasi-static electromagnetic field with the wavelength that exceeds characteristic transverse dimensions of conductor and cylinder. As the study result it is seen a satisfactory coincidence of the calculated and experimentally obtained values of the EMF of the transducer output signal in the cases of the product absence and with variety of products. As for example for measuring windings with angular coordinates φ = 30° and 60° an error of voltage values difference is less than 10%. The study shows that the advantage of such transducers while operating on one fixed frequency is capability to perform the multi-parameter testing on account of processing of certain amount of some spatial harmonics of excitation field.

The work is devoted to the development and research of the entropy criterion of image analysis on its corresponding to the method of RLE-compression. The Lab color model and the CIEDE1976 color estimation metric have been analyzed. The pixel information importance parameter has been introduced, which is based on the above described metric and allows us to estimate the importance of the adjacent pixel taking into consideration the information it introduces in relation to the previous pixel. The modified entropy image analysis criterion has been developed taking into account the pixel’s information importance parameter. The adequacy of the proposed criterion has been checked on the sample of standard test images and the feasibility of its use has been proved.

For the accredited calibration laboratories in Ukraine, a second round of inter-laboratory comparisons (ILC) of the results of calibration of electrical resistance measures of direct current was conducted. It is important to conduct such rounds of ILC of results with the involvement of an increasing number of calibration laboratories. This will, accordingly, establish the competence of an increasing number of calibration laboratories, which is quite relevant today. The article presents the results of the first round of ILC of the measures of electric resistance 1 Ohm, 10 Ohm and 100 Ohm on a direct current. As an comparison examples by reference laboratory measurement of electrical resistance of direct current P321 and P331, which were already used in the first round of ILC, were selected. The reference laboratory has research the measures of electrical resistance as a means of comparison, defined the reference values of comparison with the calculation of their extended uncertainties according to the measurement model. The comparison of the results of measurements obtained during the calibration of the measures of electrical resistance of eight laboratories took place according to the radial scheme from 2018 to 2019. The deviations of the results obtained by each laboratory were determined and their correctness was evaluated taking into account the uncertainty of measurements by one of the criteria for performance statistics for the selected electrical resistance ratings. The obtained En values show that for all laboratories participating satisfy the set criterion, except for the result of one laboratory for electrical resistance of 10 Ohms. A comparative analysis of the results of the calibration of resistance measures for laboratories that took part in the first and second rounds was carried out.
