LASER Transmitter and Receiver

LASER Transmitter and Receiver

This set of two circuits from the basis for a very simple light wave transmitter. A LASER beam is modulated and then aimed at a receiver that demodulates the signal and then presents the information voice, data, etc.. The whole thing is very easy to build and requires no specialized parts execpt for the LASER itself.
