Abstract

The invention relates to the field of spatial light transmission equipment, in particular to a laser-based space optical communication device. The laser-based space optical communication device comprises a light emission module, a light receiving module and a light transmission module, the light emission module comprises an amplification driving circuit, a light power monitor, a direct current bias and a light emitter. The light emitter is connected with the amplification driving circuit, the light power monitor and the direct current bias; the light transmission module comprises an optical conversion module and an optical detection module. The light receiving module comprises a light receiving assembly, a bias voltage circuit, a signal detection circuit and an amplification circuit. Thelight receiving assembly is connected with the bias voltage circuit, the signal detection circuit and the amplification circuit. Due to the fact that the one-way transmission performance of the laseris visual and visible, no hidden reverse link exists, and due to the fact that a laser is good in electromagnetic compatibility, high in strong electromagnetic interference resistance and the like, the spatial light communication module based on the laser has very high safety.

Description

technical field [0001] The invention relates to the field of spatial optical transmission equipment, in particular to a laser-based spatial optical communication device. Background technique [0002] With the development of science and technology, the increase in the amount of information, the implementation of the national big data strategy, the continuous expansion of data transmission requirements and application scope, network information security issues have received extensive attention. For this reason, many government agencies, military units, and companies have strengthened their efforts. Security and confidentiality measures for internal information systems. One of the important measures is to implement complete physical isolation between the internal information system and the external network. In order to prevent ferry attacks and stealing secrets, many units prohibit mobile carriers from transmitting information between external network and internal network comp...
