Abstract

The invention discloses a full-duplex free space wireless optical communication terminal machine. The full-duplex free space wireless optical communication terminal machine comprises an emission system and a receiving system. The emission system comprises a single-chip microcomputer system, a driving and modulator circuit and an illumination module, wherein the driving and modulator circuit comprises a temperature control circuit (ATC), a current control circuit (ACC), a power control circuit (APC), a protective circuit, an alarming circuit and a parameter acquisition controller. The receiving system comprises a single-chip microcomputer system, a detection and demodulation circuit and a receiving module. The wireless optical communication terminal machine is mainly applied to secure communication between an outdoor movable medium-long-distance wireless optical communication (0.1-20 km) and a naval ship.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a full-duplex free-space wireless optical communication terminal for outdoor mobile medium-distance (0.1KM-10KM) communication. Background technique [0002] Radio communication is a commonly used data communication method for coordination between field workers or ships. It is characterized by long communication distances and is not affected by weather. However, there is a fatal shortcoming in this method: poor confidentiality. Therefore, when performing combat missions, it is often necessary to keep radio silent, which will lead to the inability to realize real-time information exchange between combatants or ships, and affect coordination. [0003] The present invention proposes a mobile full-duplex free-space wireless optical communication terminal. Compared with microwave communication or wired communication, it is less susceptible to external interf...
