Digital Image Processing of Axis-Symmetric Electric Arc Plasma Based on Chromatic Modulation Methods

An integrated experimental approach is presented for processing the optical information produced from axis-symmetric electric arc plasma. The method is based on digital image processing and chromatic modulation techniques. Chromaticity changes in a number of chromatic parameters are related to changes in physical electric arc characteristics and properties (e.g. regions, temperature). The results are in the form of a chromatic contour map which shows how the overall electric arc and its environment behave and respond. Such maps show the totality of information which can be accessed about the arcing event and the level of monitoring discrimination which is achievable with the chromatic methodology in a simple and easy to understand human vision compatible manner. The suggested method provides easier data analysis and high levels of data compression.
