the first beam splitter; the spatial transmission path;
A first optical information transmission optical path is formed by sequentially passing through the second beam splitter and entering the second photodetecting element as received light, and the transmitted light is emitted from the second light emitting element. of,
the second beam splitter; the spatial transmission path;
In the optical space transmission device, the optical space transmission device forms a second optical information transmission optical path by sequentially passing through the first beam splitter and entering the first photodetecting element as received light. By tilting the light-receiving surface of the photodetecting element at a predetermined angle with respect to the optical axis of the received light, reflected light generated when the received light is incident on the light-receiving surface passes through the optical axis and passes through the first and second beams. An optical space transmission device characterized in that the optical information transmission optical path is prevented from returning to the optical path for optical information transmission.
