Abstract:
A system comprises a tracking electromagnetic beam generator, a retro-reflecting device, a signal generator, a communication electromagnetic beam generator and a receiver. The tracking electromagnetic beam generator transmits a tracking electromagnetic beam. The retro-reflecting device reflects the tracking electromagnetic beam toward the tracking electromagnetic beam generator. The signal generator generates a communication signal. The communication electromagnetic beam generator transmits a communication electromagnetic beam, based on the communication signal, to the retro-reflecting device. The receiver receives a portion of the communication electromagnetic beam as reflected from the retro-reflecting device.
