MULTISPECTRAL VIDEO SURVEILLANCE SYSTEM Russian patent published in 2025 - IPC H04N7/18 H04N23/13 H04N23/50 

FIELD: physics.

SUBSTANCE: invention relates to the field of spectrozonal television and includes the combined use of tele-thermal imaging and laser equipment and can be used in systems for remote probing of surface of objects, as well as used in systems of video surveillance and selection of objects using spectrozonal systems of technical vision. Multispectral video surveillance system provides for the formation of television and thermal imaging signals of images of objects by recording and converting a radiant flux in the visible, near, middle and far infrared regions of the spectrum, as well as obtaining signals of images of laser indication of tracking objects by recording and converting radiant flux reflected from the object in the near infrared region of the spectrum. At the same time the video surveillance system comprises a mirror-lens lens in a common structure, which includes the first, third, fourth and fifth optoelectronic channels with a matrix photodetectors for detecting a radiant flux in Δλ₁ VI-region of the spectrum, Δλ₃ zone of medium and Δλ₄ far infrared areas and Δλ₅ zone of near infrared region, as well as a second optoelectronic channel for detecting a radiant flux of external laser radiation in Δλ₂ near infrared region, with dominant wavelength λ₀, with near-infrared laser radiation photodetectors.

EFFECT: broader functional capabilities of a video surveillance system with increased reliability and efficiency of surveillance while providing tracking of objects due to formation of TV image signals in the near infrared region of the spectrum.
