What Is Free-Space Optics?

Infrared laser communication is free-space optical communication, which refers to the use of laser-generated light beams to send broadband data, voice, and video from one device to another through the air. This technology can be regarded as the optical communication wireless transmission technology equivalent to the optical communication wired transmission through the optical fiber cable. This kind of communication can effectively solve the problems of communication volume and information security. Its scope of application has gradually entered the civilian field from military, and its technology itself is also constantly improving.
