Application of chaotic oscillator to signal detection of optical current transducer

The signal detection based on chaotic oscillator applies the bifurcation behavior of the driven Duffing oscillator. Chaotic system is sensitive to certain signal and immune to noise, the properties of which improve the detection sensitivity and anti-interference capability. The outputs of optical current transducer (OCT) are weak signals, and mixed with noises. Sometimes the signals are submerged by heavy noises. In this paper, based on chaotic detection scheme, a new signal detection method of OCT is presented. The results of simulation and experiment prove this method is effective.
