This intellectual property describes a low cost sensing system with sub-centimeter spatial resolution that can be deployed under high temperature (> 1600°C), high pressure (>1000psi), highly corrosive harsh environment. This technique can be applied to enormous kinds of materials, which makes it a unique sensing technology under various circumstances. The platform offers a powerful means for real-time distributed multi-parameter measurement for turbines, coal gasifiers, aerospace shuttles as well as other industrial and biomedical systems.
