| Outline of Final Research Achievements |
Ultra-high resolution near-field scanning millimeter-wave thermography was developed to enable imaging of the temperature and/or emissivity distribution of a sample with a spatial resolution below the diffraction limit. This technique utilizes a sensitive radiometric receiver in combination with a scanning near-field microscope. Experiments were performed at a millimeter-wave frequency of 50 GHz for an aqueous solution of bovine serum albumin, which is a serum albumin protein derived from cows, in the low temperature range down to 125 K where passive imaging systems in the infrared region are ineffective. Our experiments show thermodynamics in the transition of structural states in protein as the transition in emissivity, indicating that imaging of the emissivity distribution is possible.
