Paper Abstract

We applied the spectral imaging technique to the remote sensing of physiological responses on the human body. Blood, sweat and thermal distributions and their fluctuation are important and useful information to estimate the physiological state or thermal comfort of a person. Such information can be obtained as images by using cameras which can detect different wavelength regions. The blood distribution can be observed over a 430 nanometer wavelength region by the absorption pattern of oxidized hemoglobin contained in blood. Also information of sweat distribution can be obtained over a 1.9 micrometer region by the absorption pattern of water. Thermal cameras can acquire a thermal distribution of the human body without contact. We therefore attempt to observe simultaneously blood, sweat and thermal distributions and their fluctuations by spectral imaging. Some experimental results are shown. The sensitivity of this technique is discussed.
