近红外光谱和光电体积描记法（PPG）用于测量血液成分。血液的吸收系数在不同波长下不同。该事实用于计算血液的光吸收特性，其产生关于血液成分（如血红蛋白（Hb）和动脉血氧饱和度（SpO2））的信息。所测量的PPG时间信号和峰与峰脉冲幅度之间的比率用于计算这些参数。新开发的光学传感器系统使用600 nm至1400 nm范围内的五种波长来测量血红蛋白浓度、氧饱和度和脉搏。这种非侵入式多光谱测量方法使用基于激光二极管发射的单色光辐射的原型设备进行了测试，并使用发光二极管（LED）通过手指上的皮肤区域进行测试。本研究中组装的传感器完全集成到可穿戴手指夹中。
NIR-spectroscopy and Photoplethysmography (PPG) is used for a measurement of blood components. The absorption-coefficient of blood differs at different wavelengths. This fact is used to calculate the optical absorbability characteristics of blood which is yielding information about blood components like hemoglobin (Hb) and arterial oxygen saturation (SpO2). The measured PPG time signals and the ratio between the peak to peak pulse amplitudes are used for a calculation of these parameters. The newly developed optical sensor system uses up to five wavelengths in the range of 600 nm to 1400 nm for a measurement of the hemoglobin concentration, oxygen saturation and pulse. This non-invasive multi-spectral measurement method was tested with prototype-devices based on radiation of monochromatic light emitted by laser diodes and by using light emitting diodes (LED) through an area of skin on the finger. The sensors assembled in this investigation are fully integrated into wearable finger clips.
