Laser communication using satellites represents a promising avenue for data transmission in geographically distant areas without advanced infrastructure. This approach is characterized by its high transmission rate and low power requirements, providing substantial benefits over optical fiber and radio communication. However, the optical channel should exhibit greater transparency for light transmission, resulting in a severely restricted application of this technique for information ...

Quantum key distribution via satellites enables the technology to be applied attranscontinental scale; nevertheless, in contrast to fiber systems, using a free-space opticalcommunication channel presents certain extra technological obstacles. The contribution of theacquisition, pointing and tracking system’s operation to the potential quantum bit error valueis investigated in this research. The polarization extinction ratio measurements varying ...

A satellite-constellation based global quantum network could allow secure quantum
communication between remote users worldwide. Such a constellation could be
formed of micro- or even nanosatellites, which have the advantage of being more
cost-effective than larger expensive spacecrafts. At the same time, the features of
quantum communication impose a number of technical requirements that are more
difficult to meet when ...

When data are incomplete, standard fuzzy data mining methods face an unacceptable trade-off: deleting objects with missing values loses up to a third of the sample and introduces systematic bias under the MAR mechanism, while mean imputation destroys the covariance structure and produces rules with artificially inflated support. This paper proposes a different solution - ...

This article presents a three autocollimation method (TAM) for measuring the refractive index (RI) of optical glass. The popular minimum deviation method (MDM) for RI measurement is accurate, but it is very laborious, since the procedure of determining the minimum possible angle requires many iterations. TAM allows the calculation of RI based on the measurement ...
