This group works on Optical measurement and sensing, and on plasmas for waste stream processing and corrosion/wear resistant coatings.

Optical sensing uses colormetic coatings for process control when the chemical of interest is known; spectroscopy for general chemical analysis, and interferometry for positional measurements; e.g., for stress field visualization. Optical sensors have some very desirable characteristics: they can be used in situ and in real time; they can withstand harsh environments, and tend to be self calibrating. The overlap of INEL's capabilities with the needs of the utility industry include: air emissions monitoring, T&D sensors (see above optical PT), incipient failure sensors, large sensor arrays, and material degradation history.
