Abstract

The 3-D measurement of plasma is a significant subject for analysis; development of practical methods, particularly noninvasive methods, are needed. This paper reports a new method for plasma diagnostics called light emission computed tomography, which is capable of noninvasive imaging the internal emission intensity of a 3-D source over any spectral range by sensing the visible radiation emitted by the plasma. To ensure the effectiveness of this technique, we developed a light emission computed tomography system with automatic data collection; and we performed some experiments on discharge plasmas to estimate the performance of the system. We obtained good images of radiation intensity distributions.
