The Infrared Radiometric Method and its Application to Remote Temperature Measurement

The principles of infrared thermometry are reviewed. Basic properties of infrared optical materials and detectors are presented with reference to design and performance of the radiation thermometer. Application of the radiometric method to a broad class of common industrial materials forms the substance of this paper. Recent extensions of the method to temperature measurement of flames, glass and plastics are described. Applications of special interest to the Radio Engineer are included.
