-The laser transceiver is a free space optical communication device that encodes audio on a laser beam using pulse width modulation (PWM). A single transmitter and receiver unit can be built for about $15-$20 in parts. We used to use this for a demonstration in ELEC 3030 (RF Systems Lab), but aligning the lasers took quite a bit of time to setup.+{{:​transmitter_1.jpg?​direct&​200 |}}The laser transceiver is a free space optical communication device that encodes audio on a laser beam using pulse width modulation (PWM).
