A Free Space Optical Receiver for Data detection and Radio Science Measurements

This method is an optical module to the existing opticalcommunication receiver architecture. For optical links with intensity modulated laser transmission or phase modulated CW lasercommunications the proposed optical receiver provides both data detection and signals required to extract Radio Science datasuch as amplitude, phase and frequency due to planetary atmospheric changes. We can extract the same information required forradio science data by using differential methods of encoding and at the optical receiver a local laser, a phase shifter, and an arrayof photon detectors are used.
