Abstract

Recently, free space optical communication secure links have attracted much attentions, especially in
military and defense applications; the channel of this links is atmosphere. Data are delivered on a beam of
light in free space. The atmosphere interacts with light because of the atmosphere composition. This interaction
reduces the channel stability and increases the BER. In this paper, the effects of mechanical vibrations
on the BER are evaluated. Several beam steering methods are introduced and compared with each
other. FSM beam steerer method, as the most efficient way in an autotracking system, are used and it is
shown that applying this beam steerer, the system's fluctuations are highly reduced while BER are improved.
