Abstract
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
