Free-space optical (FSO) systems have proved as the best technologies for communication and surveillance systems. These systems are merged with other technologies for providing robust applications. In FSO systems, when laser light is transmitted through the atmospheric channel, severe absorption is observed especially because of fog, snow, heavy rain etc. Therefore, we have discussed here different free space optical channel modelling techniques for mitigating these effects.
