Radiation balance microwave thermograph for industrial and medical applications

Abstract

A new improved radiometer has been developed, which measures physical temperature independently of a possible mismatch between the radiation-emitting object and the receiving antenna. Its ability to reduce a mismatch-induced error of 74% (in a conventional system) to a level comparable to the random fluctuations of the instruments output (3% or 0.3 K) has been demonstrated experimentally.
