Optical Pressure-Temperature Sensor for a Combustion Chamber

A compact sensor for measuring temperature and pressure in a combustion chamber has been proposed. Heretofore, independent measurements of high pressures and temperatures in combustion chambers have not been performed. In the original intended application, the combustion chamber would be that of a rocket engine. Sensors like this one could also be used to measure temperatures and pressures in other combustion chambers and other, similar harsh settings. There could be numerous potential applications in the aeronautical and automotive industries.
