It is also necessary to formulate endurance criteria for the structures of the video surveillance system when exposed to laser radiation. We have to develop countermeasures for small unmanned aerial vehicles that are equipped with video surveillance and video reconnaissance systems. So it is proposed to investigate the destructive effect of pulsed laser radiation on cameras of different types (CMOS, CCD, with different optics, etc.) at a distance of up to 3,000 m in laboratory and real conditions. We also must research the physical mechanisms of functional suppression of CCTV cameras when they are affected by laser systems. It is assumed to determine the threshold energy levels required to suppress the functional properties of optoelectronic systems depending on the spatial and temporal characteristics of laser radiation. Will be considered and proposed the design of protective optical elements to reduce the energy of the laser emitter on the surface of sensitive elements. The defined criteria of endurance can be useful both at implementation of own developments, and when choosing necessary elements at purchase of the corresponding systems from foreign suppliers. popup.nrat_date 2024-12-09 Close
