Two-way optical communication apparatus |
摘要 |
An optical communication apparatus that includes a polarization beam splitter which synthesizes an optical axis of a light emitting optical system having a light emission element for emitting a linearly polarized light and an optical axis of a light receiving optical axis to make the optical axis for reception coincide with the optical axis for transmission. A phase plate is provided in such a manner as to be rotatable by a predetermined angle about the common axis. An optical axis of the phase plate of each of the associated communication apparatuses is set at an adequate angle before installation thereof.
