Annotation: The paper considers distortions of video signals in active and pulse television system by noise and disturbances on the observation path. It is shown that optical nonuniformity on the observation path leads to reflected signals of infrared illumination and illuminated objects in a video image. We offer methods of reduction of video signal distortions by a pass-band optimization of a video path, chopped illumination impulses and synchronization application in active and pulse television systems.

Keywords: supervision in difficult conditions, optimum pass-band, return reflections, supervision conditions modeling, form of video signal change
