To reconvert the picture transmitted from the satellite, the analog tape controls a beam of light that scans photographic paper under control of the scanning conditions of the mirror on board the satellite. The photographic paper unwinds at a speed synchronized with that of the satellite. The intensity of the light beam is directly controlled electronically by the analog tape. Thus, a picture is reproduced, line by line, on 70 mm film.
