[ 1 ] - Investigation to Reliability of Optical Communication Links using Auto-Track Subsystems in Presence of Different Beam Divergences
In this paper, we investigate the effects of auto-tracking subsystem together with different beam divergences on SNR, BER and stability of FSO communication links. For this purpose we compute the values of power, SNR and BER on receiver, based on analytic formula of Gaussian beam on receiver plane. In this computation the atmospheric effects including absorption, scattering and turbulence are c...
[ 2 ] - Analyzing the Propagation Behavior of a Gaussian Laser Beam through Seawater and Comparing with Atmosphere
Study of the beam propagation behavior through oceanic media is a challenging subject. In this paper, based on generalized Collins integral, the mean irradiance profile of Gaussian laser beam propagation through ocean is investigated. Power In Special Bucket (PIB) is calculated. Using analytical expressions and calculating seawater transmission, the effects of absorption and scattering on beam ...
