Abstract:
1. A method of lasercomm using single wavelength, comprising: modulating a non-periodic first data onto a radio frequency (RF) carrier to produce a modulated RF carrier; intensity modulating a laser beam with the modulated RF carrier; transmitting the laser beam with the non-periodic first data modulated on the laser beam from an interrogator through the air to a modulating retro-reflector (MRR) terminal which is comprised of a receiver and an MRR unit, wherein the laser beam with the non-periodic first data is transmitted from the interrogator to the MRR terminal without using any fiber optic cables connecting the interrogator and the MRR terminal; receiving a portion of the laser beam at the receiver; re-modulating a portion of the laser beam received at the MRR unit with a second data to produce a re-modulated laser beam; and re-transmitting the re-modulated laser beam back to the interrogator.
