Abstract:

There is, at present, no commercially available non-contact device which can accurately
measure temperatures without prior knowledge of the emissivity of the material being
sampled.  A prototype pyrometer system that is capable of accurately measuring temperatures
and emissivities in the temperature range of 300 to 2000 C has been designed, constructed
and tested.  The device employs several radio-meters, each filtered to receive light
only within a narrow range of wavelengths selected to be sensitive to the temperature
and insensitive to the emissivity of the sample. The system has also been adapted
to a computerized data acquisition in order to develope data reduction software.
 This project lays the foundation for development of a space-flyable package.
