Control algorithm development for mobile FSO node alignment

Since the need for high alignment accuracy of the transmitter and receiver to construct a viable connection is a primary challenge for mobile free-space optical (FSO) links, developing an efficient transmitter control system for acquisition and tracking is an urgent demand. This paper investigates a novel control algorithm within different transmitter designs in FSO mobile networks. The fiber bundles are utilized so that the beam deflection properties of a lens can be exploited to affect beam steering. After acquiring and processing the data from GPS, fisheye system as well as the receiver, the adaptive control system would help tracking the mobile receiver and providing optimum coverage over the target area. Initial analysis of the design indicates refinements in design and performance required to develop a practical control system.
