Abstract
The present disclosure provides a free space optical system for optically transmitting processed radio frequency signals through a variably refractive medium. The system may include a transmitting element configured to receive a first signal and process it to generate a time-division combined signal. The transmitting element includes an optical source to generate a beam of light, a modulator to modulate the beam of light based on the time-division combined signal, and an amplifier to amplify the modulated beam of light, which is transmitted through the variably refractive medium. A receiving element includes a photoreceiver to receive the amplified beam of light and extract a second time-division combined signal, a correction unit to correct distortion in the second time-division combined signal, a mixer to multiply the corrected signal with a predetermined frequency signal, an amplifier to amplify the multiplied signal, and an antenna to emit a radio signal generated from the amplified multiplied signal.
