Biothermometry for Skin Surface by Using Infrared Rays and 1/fn Fluctuating Phenomena

As infrared thermography has a feature that we can diagnose two-dimensional temperature fields nondestructively and simultaneously at every picture element, it has widely been applied to various engineering and medical applications. Therefore, in this paper, a skin surface of a living body was diagnosed by sensing energy emitted from it quantitatively as electromagnetic waves using the infrared thermography. The unsteady fluctuating phenomenon was analyzed with the measured temperature data statistically. Then, human's feelings were estimated by using a spectrum analysis method and a semantic differential method. The fluctuation phenomenon representing 1/fn fluctuation is mainly focused on throughout all the study.
