Abstract
High temperature range black body techniques are combined with lower temperature range photoluminescent techniques to provide an optical method and apparatus for measuring temperature over a very wide range. Various optical probe configurations are disclosed which combine the black body and photoluminescent technologies. Signal detection and processing can be combined, and temperature measurements made by the photoluminescent technique within an overlap of the two temperature ranges can be used to calibrate measurements made in the higher range by the black body technique.
