Robust and high-temperature-capable fiber optic temperature sensors are needed to improve the efficiency and reduce the emission of greenhouse gases in power generation using fossil fuels. While these devices are commercially available, their costs are too high. A novel design for the thermal probe of a fiber optic temperature measuring system utilizing a phosphor microsphere is being proposed. If proven to be feasible, it should be possible to bring the cost of producing a high-temperature-capable fiber optic thermometer to the range of $300. The proposed fiber optic temperature sensor will find use in gasification plants, advanced combustion systems and turbines. It will also make possible the monitoring of field enabled processes for chemical synthesis, polymerization, sintering, etc.
