METHOD OF FORMING, TRANSMITTING AND RESTORING SIGNALS OF DIFFERENT-SPECTRAL IMAGES Russian patent published in 2019 - IPC H04N7/18 

FIELD: electrical communication engineering.

SUBSTANCE: invention relates to spectrozonal television using registration of reflected or emitted flux in several zones of optical spectrum. Result is achieved by the fact that after splitting of input radiant flux F(λ) into two identical streams and passing them through two broadband optical filters ΟF₁ and OF₂, spectral characteristic of which is mutually opposite and satisfies the condition F₁(λ)=1-F₂(λ) in a spectral region with a wavelength from λ₁ up to λ_n, and converting radiant fluxes using two matrix photodetectors having the same rectangular spectral characteristic in a spectral region with a wavelength from λ₁ up to λ_n, generating two initial integral image signals U₁(t) and U₂(t), further separately for first and second integral image signals U₁(t) and U₂(t) based on analysis of their current amplitude values is generated for time moment Δt_i, corresponding to one i image element, m signals of different-spectral images by sampling from a pre-prepared and stored array of data in a memory device, which include a plurality of amplitude signal values for each detection region Δλ_i, then obtained signals of different-spectrum images are processed, selecting from any m signals of different spectral images any three signals of different-spectral images, sending said signals to inputs of a color video monitoring device and displaying said signals for visual analysis, as well as automatic selection of specified objects based on analysis of distribution of amplitude values m signals of different-spectral images within spectral section with wavelength from λ₁ up to λ_n.

EFFECT: providing the possibility of generating signals of different-spectrum images for several zones of detecting a radiant flux inside a wide spectral region and increasing reliability of detection, selection and recognition of objects.
