Threshold Color Sensing Using Coupled Oscillator Networks

In this work, we examine the dynamics of a network of Colpitts oscillators which are coupled through a series of color- filtered CdSe photocells. We establish that with the analysis of particular emergent behaviors (most notably, frequency-locking within the network), this type of system has promise as a threshold color sensor. By exploiting such emergent behaviors, this type of system may find utility in optical pattern recognition.
