    Design and study of a laser system for detecting optical devices
    (ХНУРЭ, 2019) Hnatenko, O. S.; Machekhin, Yu. P.; Neofitnyi, M. V.; Gulak, S. V.
    The development of a laser system for detecting optical devices is presented in this research work. The proposed laser system is based on two principles: first, fixing glare from optical devices; second, fixation with the help of a high-sensitive photodiode of low-intensity emission, which in turn complicates the operation of counteraction systems offered for the laser system.

    Optical system recognition via topological methods
    (SPIE, 2020) Kurskoy, Yu. S.; Hnatenko, O. S.; Machekhin, Yu. P.; Neofitnyi, M. V.; Zarytskyi, V. I.
    The aim of the paper is to create a topological model for the detection and recognition of hidden optical surveillance systems. The model is based on fractal insights about the structure of the optical signal and determination of the fractal dimension intensity distribution in a cross-sectional plane of the laser pulse reflected from the target. It is shown that the approximation of the fractal dimension value to unity is a prerequisite to the target classification as an optical surveillance device. In order to classify the type of an optical device along with the fractal dimension the group of the fractal characteristics, consisting of the type of fractal signatures, the type of spatial spectrum and the values of spatial frequency that characterize the signal structure must be developed.

    The usage of lasers in military equipment. Part1.
    (LAP LAMBERT Academic Publishing, 2020) Hnatenko, O. S.; Semenets, V. V.; Neofitnyi, M. V.
    The monograph considers the possibility of using various types of lasers in optical systems for military applications: rangefinders, navigation systems, guidance and suppression systems, ABM defense and space-missile defense systems, as well as quantum data security systems. For better perception, the monograph highlights the following physical principles of lasers: gas, solid-state, free electron, and fiber. The monograph is intended for researchers, engineers and technicians engaged in research and development, manufacturing of laser devices for various purposes. It can also be useful for graduate students, students and cadets of the relevant specialties of higher educational institutions in the study of subjects related to laser and optoelectronic technology.
