Comparison and evaluation of the laser beam-shaping techniques [PDF]

open access: yesSPIE Proceedings, 2013
Over the past several decades, free-space optical (FSO) systems have gained a specific place in the wireless technology area. The application of these systems is advantageous for high bandwidths, a license free band and quick installation. The main drawback of FSO systems is their dependence on the state of the atmosphere causing deterioration of the ...
