THREE-SPECTRUM VIDEO SURVEILLANCE SYSTEM Russian patent published in 2023 - IPC H04N7/18 

FIELD: spectrozonal television with the joint use of laser technology.

SUBSTANCE: in a three-spectrum video surveillance system containing a mirror-lens lens and having first and second matrix photodetectors with optical filters transmitting a radiant flux of a certain wavelength with a width Δλ₁ and Δλ₃ and their location in the visible and thermal regions of the spectrum, with each photodetector having the design of the mirror-lens lens with blocks for mechanical adjustment of the position of the first and third matrix photodetectors relative to each other in six degrees of freedom installed on an autonomous fixed mount. A third optical electronic is additionally introduced receiving channel for recording the reflected radiant flux of external laser radiation in Δλ₂ zone of the near-infrared spectrum with the dominant wavelength λ₀ and its conversion into a signal to indicate the location of an object of interest in a television or thermal image of the observed space.

EFFECT: expansion of the functionality of the video surveillance system with an increase in the reliability and efficiency of surveillance and tracking.
