Description

Technical field:

[0001] The invention is a wireless laser communication terminal with multiple emitting light sources and automatic tracking function. The invention belongs to the communication field. Background technique

[0002] Free space laser communication technology has a wide range of applications, including: interconnection between mobile communication base stations, user access, local area network, intranet (Intranet), Internet (Internet) access, backup link, rapid deployment, temporary expansion, Disaster emergency. It becomes a better choice in places where it is inconvenient and impossible to lay optical cables, and places where it is inconvenient and impossible to erect microwave antennas. Compared with microwave communication, it does not require a frequency use license.

[0003] Radio communication using electromagnetic waves as signal carriers has a long history, among which short-wave, microwave, and millimeter-wave wireless communications are still widel...
