Abstract
Light-based deciphering and transmission of information from one remote party to another in line-of-sight is disclosed. The system speeds the pace of light-based transmissions, the decoding of transmissions, and improves the accuracy of reception of the transmissions. In certain embodiments, the system sends both visual and infrared light to send different types of information to the recipient or to send information under different conditions. Exemplary embodiments disclosed herein demonstrate three exemplary systems (mechanical, LCD, and LED) that are suitable for combination with the other components of the system as disclosed herein. In certain embodiments, the system is configured to focus on the correct light (when there are other lights in view) sending the code (e.g., Morse code or On-Off Keying) and track it.
