Abstract

This paper proposes collaborative laser beam alignment system of bilateral free space optics (FSO). Active free space optics apparatus is designed and prototyped which aligns transmission laser beam precisely. Adjustment statics is also investigated involving two techniques. A collaborative adjustment method makes it possible to connect the remote FSO apparatus using nothing but the transmission laser beam. Analytic estimation method of laser spot distribution is formulated based on the Gaussian beam optics. It helps the laser beam to reach the target receiver without feedback control.
