Data Transmission Using Visible Light

Overview

Objectives/Goals The objective of this project was to see if laser communication is possible. We believe that laser communication is possible. Methods/Materials By incorporating hardware and software, we built a device that transmit data with a laser. Binary signals are sent from computer A to the audio output transformer through the line out of the computer, the signal is then sent to the laser where it is shot out and received by the solar cell. The solar cell sends what it captured to computer B where the signals are matched to a library and then decoded. Results We can send up to eighteen binary signals at 100% accuracy. Each letter has six binary signals that goes with it so eighteen binary signals is really three letters. After eighteen signals the code starts transmitting faster than it can receive so anything above eighteen signals doesn#t get recorded at 100% accuracy. Conclusions/Discussion Our original hypothesis, is laser communication possible, was correct, we can send up to three different letters at 100% accuracy.
