摘要
Provided are a device and method for free space coherent optical communications by means of an automatic compensation for phase noise in atmosphere using a femtosecond laser optical comb, and more particularly, a device and method for free space coherent optical communications by means of an automatic compensation for phase noise in atmosphere using a femtosecond laser optical comb, in which a phase shift value due to atmospheric turbulence is obtained from reflected light of transmission light generated from a femtosecond laser optical comb and the transmission light is pre-distorted on the basis of the phase shift value, thereby pre-compensating, in a transmission end, for phase noise due to atmospheric turbulence.
