Free-space optical communication (a new trend in future communication technology)

Free-space optical communication (FSOC) is an emerging communication technology that uses optical waves to transmit information, combining optics and communication technologies to bring new possibilities to the field of communications. As technology continues to advance, free-space optical communication is gradually becoming a focus of attention. This article will introduce the definition, principles, applications, and future trends of free-space optical communication.

Free-space optical communication is a method of transmitting information using light waves in space. Compared to traditional wired communication, free-space optical communication offers higher transmission speeds and greater bandwidth. It is not affected by electromagnetic interference, can achieve longer communication distances, and has lower energy consumption and higher security.

Free-space optical communication mainly relies on laser-generated laser beams to transmit information. Laser beams have high directionality and focus, allowing for the transmission of information over long distances in space. At the transmitting end, information is encoded and converted into optical signals, which are then transmitted by the laser as laser beams. At the receiving end, the optical signals are received and decoded back into the original information.
