Paper Abstract

The potential application of near-infrared spectroscopic imaging technologies in the field of medical diagnosis for observing the sweat distribution on the skin was considered, which is based on the absorption characteristics of water to light energy at the wavelength of 1.94 micrometers . This is an approach on applications of optical sensing technologies and visual technologies of information processing in the sweat distribution detection. Recently we developed such an optical sensing system to investigate the feasibility of measuring sweat distribution on the skin. We gave a direct function expression related to the water or sweat content and the gray level of the image. We demonstrate the configuration of our system and give an experimental evaluation of the light absorption coefficient of water. Using this system we actually measured the sweat distribution on the face in order to evaluate the effectiveness of this sensing technology applied in the field of medical diagnosis. Several measured results are presented and discussed.
