FIELD: physics, image processing.
SUBSTANCE: invention concerns television technology and can be applied in optical electronic data processing and recognising systems. The objective is achieved by preliminary processing involving replacement of interconnected fiber couplers in spatial filters by independent couplers connected by optical combiners, which maintain filter factor symmetry and linear filter frequency response of spatial filters. Object of invention includes spatial filtration due to factored combination of optic signal from adjoining image elements via Y-shaped optic splitters, independent electric-powered fiber couplers and optical combiners.
EFFECT: elimination of image distortions.
