Abstract

The invention discloses a free space duplex communication optical assembly. The free space duplex communication optical assembly comprises a tube base and a tube cap; a light receiving assembly, a light emitting assembly and a controller are arranged on the upper surface of the tube base. The light receiving assembly and the light emitting assembly are connected with the controller through wires,the tube cap is arranged on the upper surface of the tube base in a buckled mode and provided with a containing cavity; the light receiving assembly, the light emitting assembly and the controller aresealed in the containing cavity; the top of the tube cap is provided with a light transmitting window, and the receiving face of the light receiving assembly and the emitting face of the light emitting assembly face the light transmitting window. According to the free space duplex communication optical assembly, the light receiving assembly, the light emitting assembly and the controller only need to be fixed on the supporting surface; light receiving and emitting signals are emitted out or emitted in through the light-transmitting window, free light receiving and emitting communication of the light signals is achieved, the light emitting angle of the light assembly is large, the light receiving assembly and the light emitting assembly do not need to be matched with various workpieces foralignment operation, the structure is simple, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to an optical communication device, in particular to a free-space duplex communication optical component. Background technique [0002] Traditional optical modules are based on optical fibers for information transmission, which requires wiring of optical fibers, investment in optical fiber costs, and alignment of optical fibers with optical transceiver modules to ensure optical transmission. The structure is complex and the assembly is cumbersome. [0003] In addition, the typical size of the optical antenna used in the traditional space optical communication system is about 300mm*300mm*600mm, and the weight is about 15Kg. Larger in size and weight. And before communication is established, it is necessary to use auxiliary optical systems such as tracking devices, gun sights, or telescopes to debug the optical path. The required auxiliary optical system is large in size and takes a long time to debug, which takes about tens of min...
