  1. 154. Performance Evaluation of the 'Cat-Eye' Effect Induced by a Laser System for Locating Optical Systems
    Prof. Yaroslav Sharlovych (Institute of Physics of NAS of Ukraine)

    Oral

    The increasing availability, ease of deployment, and simple masking of optical surveillance systems persistently raise the challenge of detecting such systems. This study explores the potential of active detection based on the retroreflection (cat-eye) effect, even under challenging illumination conditions such as bright daylight.

    The proposed method relies on active laser retroreflection,...

    Oral

    The global challenge of rising terrorism has been further complicated by the war in Ukraine, which has led to extensive contamination of soil and water resources with explosives and their byproducts. This situation underscores the urgent need to develop a sensitive, rapid, low-cost, portable, and easily mass-produced sensor for explosive detection.

    A promising approach for detecting various...

  3. 170. Quantitative Surface Texture Metrology via Single-Image Statistical Analysis of Laser Speckle
    Artem Sachko (Ukrainian Physics and Mathematics Lyceum of Taras Shevchenko National University of Kyiv)

    Oral

    Laser speckle, a phenomenon resulting from the scattering of coherent light from a rough surface, is rich with information encoding the surface's micro-topography. This work presents a novel optical methodology that decodes this information for quantitative, non-contact surface texture analysis from a single, static speckle. Our approach bypasses the temporal and mechanical constraints of...

    Oral

    The influence of laser irradiation on the electrochemical properties of porous carbon material (PCM) doped with Er and Cr, as an electrode material of supercapacitors, was established from the analysis of impedance spectroscopy data. It has been experimentally shown that the specific capacitance of supercapacitors with electrodes of PCM doped with Er and Cr, increases by 40% and 60%,...

  5. 178. Application of laser Doppler vibrometry for detection of objects buried in the soil
    Dr Lyudmyla Borkovska (V. Lashkaryov Institute of Semiconductor Physics of NAS of Ukraine)
    07/11/2025, 10:00
    Oral

    Laser Doppler Vibrometry (LDV) is a modern technology for measuring mechanical vibrations of different amplitudes with high precision and without physical contact. It finds wide applications in industry, engineering, scientific research, biology, and medicine. The remote nature of LDV operation allows measurement of vibrations in hard-to-reach or hazardous locations. Specifically, it can be...
