摘　　要：为了验证基于光声效应的无创血糖检测方法,应用分子振动原理分析了葡萄糖分子的近红外吸收光谱和吸收峰,对组织内含有相同官能团的几种分子的红外吸收峰进行了比较,分析了由光谱重叠导致的干扰问题.通过实验验证了葡萄糖水溶液对800nm～1100nm近红外波段光的吸收的强弱,在970nm波长处得到了最强的声压信号.In order to validate the noninvasive blood glucose detection method based on optoacoustic effect, the absorption spectrum and absorption peaks of glucose molecules in the near infrared spectral region are analyzed according to the principle of molecular vibration. The infrared absorption peaks of several molecules containing similar functions in human tissue are compared with each other. The molestation due to spectrum overlapping is analyzed. The absorption intensity of glucose solution in the spectral band from 800nm to 1100nm is validated experimentally and the strongest acoustic pressure signal is obtained at the wavelength of 970nm.
