Communication device between fixed station and terminal station utilizing optical beam

Abstract

Abstract PURPOSE:To make the mobility of a terminal station easy by performing communication with an optical beam between a fixed station and a terminal station to eliminate the need for the connection of optical fiber. CONSTITUTION:A turning reflecting means 11 of a fixed station 1 turns independently around two orthogonal axes in response to a prescribed position of each terminal station and reflects an optical beam generated from an optical beam generating means 2 sequentially to each terminal station. The optical beam is modulated by prescribed information by means of an information transmitting means 23 and an information receiving means 26 extracts required information from the optical beam returned from each terminal station. Each means is controlled by a control means 4. On the other hand, an information receiving means 35 of a terminal station extracts required information from the irradiated optical beam from the station 1. An information transmitting means 36 modulates the optical beam by prescribed information and since the beam is reflected in the same direction as the incident direction at the reflecting means 31, the information is exchanged between the station 1 and the terminal station. Thus, the terminal station is moved easily because no optical fiber is connected.
