Send Music Over a Laser Beam

“This project demonstrates the use of laser in optical communications. the project consists of a transmitter and receiver that will support a one-way communications link between two separate locations. It is mainly built from a few ICs, operational amplifiers and transistors. It is possible to transmit music, voice and data. The laser used in the transmitter is a simply a laser diode that it used in cheap laser pointers and at the receiver, the laser sensor is a photo-diode.”
