A self-aligning system of single transmitter multiple receivers to design a multiplexer like a channel that transmits data over the free space opticallink[1]. The system is divided into two sectors. One is the channel over which the communication of transmitters and receivers occur. The second part of the system provides alignment control which bypasses the need for manual alignment of transmitter and receiver. Now as the communication is a point to point[6], thus the second phase of the project is very sophisticated as even a single shift in angle can cause disruption in communication.
