Abstract
The initial installation of free space optics system requires to adjustment of transmission laser beam which travels more than hundreds of meters from the transmitter to the receiver. The authors have prototyped a free space optics system that transmits thin-diameter 1550 nm laser beam at 1 Gbps. This paper proposes the method of adjusting the optimal alignment by scanning laser beam in a spiral. It also conducts some experiments on automated alignment of optical axis with respect to free space optics devices to reveal the effectiveness of our proposed automatic optical alignment tactics.
