中文摘要	通过精确测量光子密度波的相位延迟和幅度衰减,借助于一个光学参数已知的校准模型,可以定量检测组织的光学吸收参数和约化散射系数通过测量多个波长下组织的吸收系数,就可以进一步求解出人体局部组织的血氧饱和度血液-酵母溶液仿真模型和前臂动脉阻断实验的结果都表明该三波长的频域近红外光谱系统可以实时定量地检测组织氧饱和度的动态变化情况; A three-wavelength frequency-domain photon migration spectroscopy instrument using in-phase and quadrature (I&Q) demodulation technique in a 140-MHz homodyne system was described here. A calibration procedure was employed to qualify absorption coefficient and reduced scattering coefficient with single source-detector separation. The performance of the frequency-domain NIRS to quantify blood oxygen saturation and the concentration of oxy-and deoxy-hemoglobin is examined with experimental measurements on a yeast-blood model. The results of the forarm arterial occlusion experiment was in good agreement with those measured by the Time-resolved Spectroscopy.
