A review of free space optical communications systems is presented. Communication topics such as modulation and detection are discussed in relation to optical links. Negative channel effects such as scattering and absorption are investigated with respect to their impact on the channel and the associated bit error rates. The challenges posed by atmospheric disturbances are considered. New sources and detectors in transmitter and receiver circuits are proposed. Finally, power link budgets are prepared for free space systems to illustrate the losses incurred during transmission.

Abstract


A review of free space optical communications systems is presented. Communication topics such as modulation and detection are discussed in relation to optical links. Negative channel effects such as scattering and absorption are investigated with respect to their impact on the channel and the associated bit error rates. The challenges posed by atmospheric disturbances are considered. New sources and detectors in transmitter and receiver circuits are proposed. Finally, power link budgets are prepared for free space systems to illustrate the losses incurred during transmission.
