PURPOSE: To always accurately adjust the optical axis of an optical space transmission equipment without depending on the constitution precision of an optical system. CONSTITUTION: The optical system of the optical space transmission equipment integrated for transmission and reception consists of a transmission optical system 104, a reception optical system 105, and an emitting direction detection optical system 106. The transmission optical system 104 is held in an optical system enclosure freely turnably in two orthogonal axial directions in the face perpendicular to the optical axis of emission, and the reception optical system 105 is fixed to the optical system enclosure. The optical system enclosure is held in a device enclosure freely turnably in two orthogonal axial directions in the face perpendicular to the optical axis of the reception optical system 105. The optical axis of the reception optical system 105 is controlled in accordance with the convergence position of incident light on a position detection element 5B, and the optical axis of the transmission optical system 104 is controlled in accordance with incidence information of scanning exiting light to the destination device and the convergence position of exiting light on a position detection element 5A of the emitting direction detection optical system 106. |
