| 英文摘要 | An optical space transmission apparatus for use in conjunction with an optical space transmission line (8) for carrying transmission light and reception light comprising an information transmission light emitting element (5) for generating transmission light, an optical transmission system (6,7) including an optical transmission fiber (7), an information reception light receiving element (9) for detecting reception light, an optical reception system (4), and a transmission/reception common lens (3) which is optically coupled to said optical space transmission line (8), characterized in that an end portion (7a) of said optical transmission fiber (7) is positioned near the focal plane of said transmission/reception common lens (3) and near, or on its optical axis, the transmission light emitting from said information transmission light emitting element (5) is transmitted into the optical space transmission line (8) through said optical transmission system (6,7) and through said transmission/reception common lens (3), and the reception light, carried by said optical space transmission line (8) is introduced into said information reception light receiving element (9) through said transmission/reception common lens (3) and through said optical reception system (4), whereby the transmission light and the reception light are spatially split near the end portion (7a) of said optical transmission fiber (7) which is closest to the transmission/reception common lens (3). |
