Outline of Final Research Achievements

We study nonlinear synchronization method by visible light communication in the deep sea. This model is RC circuit and switch. If the characteristics of the electronic circuit due to water pressure change. It will be considered that nonlinear synchronization occurs in the circuit.
Also, we created a microcomputer firefly that can be synchronized with visible light.The system consists of a microprocessor, blue / green LED and photodiode. Blue light performs nonlinear synchronization and becomes a clock for communication. Green light is data of 4 PPM signals. We changed the time constant of the circuit characteristics and investigated the range where synchronization occurs and the range that can communicate. The nonlinear synchronization make possible over a wide range, the synchronization and the communication.
By introducing ATC, communication at a maximum distance of 600 mm became possible.
