METHOD OF REGISTRATION AND FORMATION OF SIGNALS OF MULTI-SPECTRAL IMAGES Russian patent published in 2018 - IPC H04N5/30 G01J3/51 

FIELD: physics.

SUBSTANCE: invention relates to the field of multispectral television and concerns a method for recording and generating signals of multi-spectral images. Method includes the registration of the radiant flux in a wide spectral region from λ₁ to λ_n, its splitting into two identical streams and their transmission through two broadband optical filters OF₁ and OF₂, their spectral characteristics cover the spectral region from λ₁ to λ_n and satisfy certain conditions. Radiant fluxes are converted using matrix photodetectors and form two integral signals in the spectral region from λ₁ to λ_n. Based on the received signals, the values of the signals for the registration areas of the radiant flux in the spectral region from λ₁ before λ_n by processing signals based on solving a system of linear equations with two unknowns. Then, the received signals of multi-spectral images are processed and used for visual or automatic analysis of video information.

EFFECT: technical result is to increase the signal-to-noise ratio.
