近红外光谱成像技术在医学诊断领域的潜在应用被认为是基于水对波长为1.94微米的光能的吸收特性，用于观察皮肤上的汗液分布。探讨了光学传感技术和视觉信息处理技术在人体汗液分布检测中的应用。最近，我们开发了这样一个光学传感系统，以研究测量皮肤上的汗液分布的可行性。给出了汗液含水量与图像灰度值的直接函数关系式。我们展示了我们的系统的配置，并给出了水的光吸收系数的实验评价。使用该系统，我们实际测量了面部的汗液分布，以评估这种传感技术应用于医疗诊断领域的有效性。几个测量结果进行了介绍和讨论。
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.
