OPTIC SCANNING SYSTEM Russian patent published in 1994 - IPC

FIELD: optic instrument engineering. SUBSTANCE: system has a reflective drum rotatable about axis 2, first objective component, reflective light-splitting prism 4, two second components of the objective, second component 5 being optically coupled with radiation receptor 6 and second component 7 being optically coupled with receptor 8; two antireflective coatings different in spectral transmission characteristics applied onto outer surfaces of the lenses of first component 3 the boundary of which passes in the direction of a diameter orthogonal to rotation axis 2 of drum 1 and optically coupled with rib 10 of prism 4; antireflective coatings applied onto outer surfaces of the lenses of second components 5 and 7 with a spectral transmission maximum in the sensitivity region of corresponding radiation receptors 6 and 8. EFFECT: improved quality. 2 cl, 2 dwg
