“…An obstacle affecting a large portion of one channel's optical field would give little impact on the other channel; thus, the total required power will not fall below the minimum. Additionally, FSO systems are mounted on buildings and towers; hence, building/tower sway causes beams to wander on the detector plane [48]. Strong winds, frequent heating and cooling, and tiny movements over time are the major factors in this kind of sway.…”

“…in the LOS of the FSO system. These types of interruptions can effectively be mitigated by employing multiple input and multiple output (MIMO) FSO transmission/reception system [27,39]. Today's FSO system consists of redundant MIMO transmit-receive optics to eliminate the interference of objects such as birds, insects etc.…”

“…Έτσι για την αντιμετώπιση αυτών των φαινομένων έχουν προταθεί και μελετώνται οι τεχνικές διαφορικής λήψης (spatial diversity), όπως ακριβώς χρησιμοποιούνται στα RF τηλεπικοινωνιακά συστήματα για αύξηση της χωρητικότητας και τη βελτίωση της μετρικής του μέσου ρυθμού σφάλματος [117], [118], [120], [121], [243]- [246]. Η διαφορική λήψη μπορεί να πραγματοποιηθεί στο χώρο και συγκεκριμένα στον δέκτη [247] Όλα τα παραπάνω συστήματα κεραιών έχουν μελετηθεί και στην περιοχή των FSO και συγκεκριμένα SIMO FSO [118], [120], [121], [244], [249], MISO FSO [120], [126], [250], [251] και MIMO FSO [125], [127], [252]- [254]. Επίσης, διαφορική λήψη στα FSO συστήματα έχει μελετηθεί και ως προς το μήκος κύματος, με έναν σύνθετο εκπομπό που αποστέλλει την ίδια πληροφορία σε διαφορετικά μήκη κύματος που λαμβάνονται από δέκτες που ανιχνεύουν ο καθένας ξεχωριστά μήκη κύματος [113], [115], [116].…”
