Abstract:

Real-time principal component analysis of an atmospheric pressure plasma electrical (current, voltage and drive frequency) parameters is reported. Lissajous figure phase-space projection of the current and voltage waveforms and linear transformation of the electrical parameters on a Loading plot is also performed. Using LabVIEW graphical programming it is shown that the Lissajous figure captures a snap-shot of the plasma chemistry in the form of current waveform micro-scale events. The Loading plot provides a time-evolving view of the process that enables differentiation of plasma modes (bifurcation) and chemistry.
