我们将光谱成像技术应用于人体生理反应的遥感。人体血液、汗液和热的分布及其波动是评价人体生理状态或热舒适性的重要信息。这样的信息可以通过使用能够检测不同波长区域的照相机作为图像来获得。通过血液中所含的氧化血红蛋白的吸收模式，可以在430 nm波长区域上观察血液分布。此外，还可以通过水的吸收模式获得1.9微米区域内汗液分布的信息。热成像相机可以在没有接触的情况下获取人体的热分布。因此，我们试图同时观察血液，汗液和热分布及其波动的光谱成像。给出了一些实验结果。讨论了该技术的灵敏度。
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.
