Abstract
A high‐temperature optical sensor scheme, based on the cross referencing between a fluorescence lifetime measurement and a blackbody radiation measurement, has been developed. Results are presented indicating the value of this scheme over a wide sensing range and measurements are achieved from room temperature to 900 °C. The measurement resolution over the range and practical applications are discussed.Keywords
