Abstract

This paper intends to demonstrate wireless transfer of an audio signal via a coherent optical signal in free space between two independent systems. The principle behind said communication is conversion of audio signal to light signal via the application of modulation and amplification into a high intensity laser source that is detected by a photovoltaic cell and is then demodulated and amplified back to the audio signal.
