At the source, the visible or IR energy is modulated with the data to be transmitted. At the destination, the beam is intercepted by a photodetector, the data is extracted from the visible or IR beam (demodulated), and the resulting signal is amplified and sent … Free Space Optics Communications definition sponsored by WhatIs.com, powered by WhatIs.com an online computer dictionary
