15 November 1979 Cavity Radiometer Reflectance
Author Affiliations +
The evolution of absorbing surfaces for electrically calibrated radiometers, and techniques for measuring their absorptance (reflectance) are described. A new reflectometer for cavity reflectance measurements, which is based on a ring-shaped silicon photodiode, is described. The results of reflectance measurements on a series of cavities which represent the evolution of cavity technology are presented, and the significance of the results for future research are discussed.
