    • Algorithm and mathematical model for geometric positioning of segments on aspherical composite mirror 

      Conquet, B.; Zambrano, L. F.; Artyukhina, N. K.; Fiodоrtsev, R. V.; Silie, A. R. (БНТУ, 2018)
      In recent years, the largest terrestrial and orbital telescopes operating in a wide spectral range of wavelengths use the technology of segmented composite elements to form the main mirror. This approach allows: to expand the spectral operating range from 0.2 to 11.0 μm and to increase the diameter of the entrance pupil of the receiving optical system, while maintaining the optimal ...

    • Method for Increasing of Lens Gluing Technological Process Efficiency and a Reliable Evaluation of Output Controlled Parameters 

      Fiodоrtsev, R. V.; Metelskaya, E. A.; Marchik, V. A.; Kuznetsov, A. V.; Makarevich., A. E. (БНТУ, 2022)
      The use of glued lens components in optical devices improves the image quality of telescopic and photographic lenses or inverting systems by eliminating a number of aberrations, and also reduces light losses in the optical system of the device. The traditional production process of lenses gluing involves the sequential execution of a set of technological operations and takes a ...

    • Synthetic Aperture Orbital Telescope for Earth Remote Sensing Equipment 

      Kozhevnikov, D. A.; Fiodоrtsev, R. V.; Silie, A. R. (БНТУ, 2018)
      The object of the research is the development of the method of aperture synthesis of a mirror system designed for remote sensing of the Earth. The analysis of existing methods for the formation of the synthesized aperture was carried out, their accuracy, cost, and mass-dimensional characteristics were evaluated. A new version of the optical system of the synthetic aperture mirror ...
