<p>PURPOSE:To provide a device enabling the focusing of radio wave and light wave respectively on a primary radiator for radio wave and a light wave detector by a separating plate for separating the path of radio wave and light wave without disturbing the phase distribution on the of a radio wave antenna in a transmitter-receiver with a parabolic reflector used in common for radio wave and light wave. CONSTITUTION:A parabolic reflector 2 is used in common for radio wave and light wave. A primary radiator 1 for radio wave is installed at the focus of the parabolic reflector 2, and a light wave detector 3 is installed near the vertex of the parabolic reflector 2, opposedly to the primary radiator 1. The path of radio wave and light wave is separated by a separating plate 7 almost as large as the parabolic reflector 2 and having a light wave reflecting film of the specified diameter at the center part. This results in obtaining a transmitter- receiver without the degradation of a radio wave radiating characteristic while installing the separating plate 7 for separating radio wave and light wave, on the aperture plane of an antenna.</p> |
