Visualization 1 demonstrates the full-duplex wireless laser communication system performing real-time video communication in free space. The system accomplished real-time video communication at a distance of 120 m with a transmission rate of 10 Mbps, at which time the ND value of the receiver’s APD’s front neutral density filter was 2000. In Visualization 1, the video of a person walking captured by the opposite camera is transmitted through the system and displayed on the computer screen in real time.
