FIELD: electronics.
SUBSTANCE: method of generating of multispectral video signals includes recording of reflected or emitted by the flow in several zones of the optical spectrum. At that after splitting of input radiant flux into two identical fluxes; each of them is passed through broadband optical filters OF1 and OF2. Thus, spectral characteristic of the first OF1 covers a wide spectral section from λ1 to λi, a spectral characteristic of the second OF2 covers a wide spectral section from λ1 to λi+1, which satisfy the condition on the width of the zone of registration in the form of (λi+1-λ1) > (λi-λ1). Then convert radiant fluxes and generate two multispectral video signals U1(λ) and U2(λ). Fulfill subtraction of the first zone signal from the second one and form amplitude values of the third zone signal U3(λ), which correspond to more narrow zone of registration (λi+1-λi). After that process multispectral video signals and analyze them.
EFFECT: technical result consists in provision of high signal/noise ratio by registration of input radiation flux in a wide spectral interval zones with formation of additional multispectral signals in narrow areas of registration of radiation flux to increase accuracy of selection and recognizing of objects.
