摘要
A method and apparatus for undertaking a non-contacting measurement of the three-dimensional temperature distribution in a non-uniform examination subject direct microwave radiation at the examination subject, detect the three-dimensional phase and amplitude of microwave radiation which is attenuated and scattered by the examination subject, and calculate the three-dimensional dielectric constant distribution in the examination subject on the bases of the detected phase and amplitude values. In a separate step the characteristic thermal radiation of object is measured, too. The three-dimensional temperature distribution of the examination subject is then calculated from both the three-dimensional dielectric constant distribution data and the characteristic thermal readiation data of a selected location.
