Plasma coating describes an industrial production process in which components of all kinds are coated with thin layers of different materials. In order to receive high quality results it is of interest to obtain a homogenous layer based on a consistent composition. The information on the compounds of a plasma arc can potentially be retrieved using hyperspectral imaging.
However, plasma coating is a high speed process which demands not less than a near real-time analysis, making it impossible for push-broom sensors to be used here. Hyperspectral snapshot cameras by contrast can contribute for such an optimization.
